Entanglement is solely a quantum property and it can be extremely helpful to test the physics beyond the Standard Model in tabletop experiments with the advent of future quantum technologies. In this work, we provide an entanglement-based partial positive transpose (PPT) witness for Yukawa-type potentials in the infrared regime between pairs of neutral/charged particles in a spatial quantum...
The MAgnetized Disk and Mirror Axion eXperiment (MADMAX) is a future experiment aiming to detect dark matter axions from the galactic halo by resonant conversion to photons in a strong magnetic field. It uses a novel concept based on a stack of dielectric disks in front of a mirror, called booster, to enhance the potential signal from axion-photon conversion over a significant mass range. In...
Haloscopes are sensitive detectors used for dark matter axion search in the microwave energy range. They rely on the axion to photon conversion in a static magnetic field, and its amplification by resonance with a cavity electromagnetic mode. While simple cylinder cavities working below below 1 GHz can provide large volume detectors of typically a hundred liters or more (GrAHal-CAPP), searches...
LUX-ZEPLIN (LZ) is a direct detection dark matter experiment located at the Sanford underground research facility in Lead, South Dakota, USA. LZ utilizes a dual-phase time projection chamber containing 7 tonnes of active xenon surrounded by veto systems to search for signals induced by WIMP dark matter candidates. Recently, the experiment announced world-leading WIMP results achieved over 280...
The search for dark matter (DM) remains one of the most pressing challenges in modern physics. Detecting sub-GeV DM particles poses significant challenges for traditional Earth-based detectors due to their low collision energies. This talk presents a novel approach to overcome these limitations: blazar-boosted dark matter (BBDM). I will explore how active galactic nuclei (AGN) with jets...
Fermionic asymmetric dark matter (ADM) can be captured in neutron stars (NS) via scatterings with the neutron star material. The absence of DM annihilations due to their asymmetric nature would thus lead to their accumulation in the NS core, which can exceed the Chandrasekhar limit to collapse into a black hole (BH), and provide exclusion limits from observations of neutron stars today. We...
The LUX-ZEPLIN (LZ) experiment is a dark matter direct detection experiment operating almost a mile underground at the Sanford Underground Research Facility in Lead, South Dakota. LZ uses a 7 active-tonne dual-phase xenon time projection chamber primarily designed to detect weakly interacting massive particles (WIMPs), a well-motivated class of dark matter candidate. This talk will give the...
We investigate the phenomenological prospects of the Two Higgs Doublet and Complex Singlet Scalar Extension (2HDMS) in the context of dark matter (DM) and Higgs phenomenology. The 2HDMS provides an enlarged Higgs sector along with a DM candidate. In this work, we perform an exhaustive scan to find representative benchmarks which are consistent with all theoretical and experimental constraints....
Determination of the nature of dark matter is one of the most fundamental problems of particle physics and cosmology. This talk presents recent searches for dark matter particles from the CMS experiment at the Large Hadron Collider in mono-X signatures.
The BESIII experiment is taking data at a symmetric $e^+e^-$ collider operating at the center of mass energies from 2.0 to 4.95 GeV. With the world’s largest on-threshold production data set of $J/\psi$ (10 billion), $\psi$(3686) (2.6 billion), and 20 $fb^{-1}$ of $\psi(3770)$ decaying into D meson pairs, we are able to search for various dark sectors particles produced in $e^+e^-$...
Despite the success of the Standard Model (SM) there remains behaviour it cannot describe, in particular the presence of non-interacting Dark Matter, which composes a significant fraction of the Universe’s matter. Many models that describe dark matter can generically introduce exotic Long-Lived Particles (LLPs). The proposed ANUBIS experiment is designed to search for these LLPs within the...
In this talk (poster), we perform a feasibility study to probe dark matter production at the LHC, using a $U_L(1)$ scotogenic model. The study is conducted considering the viable parameter space of the model allowed by experimental constraints such as neutrino masses, the Higgs to invisible branching fraction, and dark matter observables. The analysis is carried out using the Markov Chain...
Models of inelastic (or pseudo-Dirac) dark matter commonly assume an accidental symmetry between the left-handed and right-handed mass terms in order to suppress diagonal couplings. Moreover, they often introduce a gauge symmetry spontaneously broken by the introduction of a dark sector version of the Higgs mechanism. Removing the requirement of such an accidental ad-hoc symmetry instead...
We study the possibility for large volume underground neutrino experiments
to detect the neutrino flux from captured inelastic dark matter in the Sun.
The neutrino spectrum has two components: a mono-energetic "spike" from
pion and kaon decays at rest and a broad-spectrum "shoulder" from prompt
primary meson decays. We focus on detecting the shoulder neutrinos
from annihilation of...
SABRE is an international collaboration that will operate similar particle detectors in the Northern (SABRE North) and Southern Hemispheres (SABRE South). This innovative approach distinguishes possible dark matter signals from seasonal backgrounds, a pioneering strategy only possible with a southern hemisphere experiment. SABRE South is located at the Stawell Underground Physics Laboratory...
The particle nature of dark matter remains a key unanswered questions in modern physics, despite it making up the majority of matter in the universe. The NEWS-G collaboration is searching for light dark matter candidates using a gaseous detector, the spherical proportional counter. The use of light gaseous targets, including H, He, Ne, etc., combined with a low energy threshold, enable access...
We investigate the phenomenology of a dark sector, extension of the neutrino sector, that simultaneously provides a viable dark matter (DM) candidate, reconciles cosmological constraints with active neutrino masses possibly measurable in laboratories such as KATRIN, and yields near-future testable predictions.
The dark sector comes into thermal equilibrium with Standard Model neutrinos after...
The dark photon is a popular choice when considering a portal between the Standard Model and the dark sector. In this work, we revisit the exclusion constraints on the dark photon, using the latest electroweak precision data from the Particle Data Group, and explore the impact on these constraints due to the CDF measurement of the W boson mass. In addition, we set upper bounds directly on dark...
The MilliQan experiment is an ongoing search for millicharged particles (mCPs), which arise naturally in many Dark Sector models which offer potential Dark Matter candidates. The experiment is located just above the CMS experiment at the LHC and leverages this proximity along shielding from most standard model backgrounds to gain sensitivity to mCPs in the mass range of $0.01-45...
One of the LHC's priorities, following the discovery of the Higgs boson, is to observe the production of Higgs pairs and to measure the Higgs tri-linear coupling $\lambda_{3H}$.
Due to the rarity of di-Higgs production, measuring $\lambda_{3H}$ has proven to be highly challenging. Exclusion limits have been observed using a variety of approaches, including cut-based methods and boosted...
The strong coupling $\alpha_s$ is the most important parameter of Quantum Chromodynamics (QCD) and therefore it is essential to determine it with high precision. This work presents an improved approach for extracting $\alpha_s$ comparing numerical lattice QCD simulations to the perturbative expansion of the QCD color-singlet static energy. We "R-improve" the $\mathcal{O}(\alpha_s^4)$...
I will present our experience with the production, recording, and publication of a series of 15 short outreach videos about Particle Physics, in Brazilian Portuguese, in the format of Instagram reels. The videos cover different aspects of our research work at the University of Sao Paulo (Brazil), where I lead a group dedicated to QCD and Particle Physics. We produced videos with different...
Precision measurements by AMS reveal unique properties of cosmic charged elementary particles. In the absolute rigidity range ~60 to ~500 GV, the antiproton flux and proton flux have nearly identical rigidity dependence. This behavior indicates an excess of high energy antiprotons compared with secondary antiprotons produced from the collision of cosmic rays. More importantly, from ~60 to ~500...
Discrepancies between experimental measurements and Standard Model predictions in B-meson decays, especially in lepton flavor universality ratios like $R_{D^{(*)}}$, $R_{J/\psi}$ and branching ratios for processes like $B\rightarrow K^*\nu\bar{\nu}$, suggest possible new physics (NP). In this study, we use an effective field theory framework, assuming NP effects only affect a single generation...
The Mu2e experiment is designed to investigate the CLFV through the observation of a neutrinoless muon-to-electron conversion in the field of an Al nucleus. The observation of such a process would be clear evidence of physics beyond the standard model. Due to the rarity of this process, a cutting-edge, intense muon beam is required to achieve an improvement of the current single-event...
A new LEGO model of the ATLAS detector has been developed to aid and enhance educational outreach. Comprising over 21,000 LEGO elements and measuring over 1m in length, this accurate 1/50 scale model depicts ATLAS as it will appear in the High-Luminosity LHC (HL-LHC) era. Cutaway walls clearly reveal every component of the real detector, from the muon chambers down to the ITk Strip Detector...
T2K is a long-baseline neutrino oscillation experiment in Japan, featuring SuperKamiokande as a far detector and a near detector complex. The primary near detector, ND280, has recently undergone an upgrade, incorporating three new sub-detectors: the SuperFGD (SFGD), two High-Angle TPCs (HATs), and a Time-Of-Flight (TOF) system.
In this poster, we present the TOF detector, which consists of...
Neutrons constitute a major background in direct dark matter searches, yet previous measurements at LNGS have reported notable discrepancies in both flux values and energy spectra. These inconsistencies arise from variations in detector technologies, calibration methods, and energy windows used in different studies. Precise knowledge of this background is necessary to devise shielding and veto...
Experimental verification of the Higgs trilinear self-coupling is one of the next major challenges of particle physics. While prospects from proton-proton collisions have centred around measuring the on-shell single- and di-Higgs production processes, the off-shell Higgs production process has also been suggested as a complementary channel to resolve the degeneracy in Higgs couplings. We...
In the High-Energy Physics field there is an active search of the origin and the nature of the Ultra-high energy cosmic rays. These are messengers that carry information from far into the Universe, and they might also hint on direction towards new physics. This talk presents the overall hardware and software design, and the construction and calibration of DUCK (Detector system of Unusual...
The muon-to-electron (µ-e) conversion corresponds to the charged lepton flavor violating process, in which a muon captured by an atom converts into a single electron with constant momentum of 105 MeV/c in the case of an aluminum target. The COMET (COherent Muon-to-Electron Transition) experiment at J-PARC is going to search for µ-e conversion in aluminum, aiming for a sensitivity of 10⁻¹⁷,...
In this contribution, we present the machine learning-based strategy to improve the reconstruction of neutral meson events within the Large Hadron Collider forward (LHCf) experiment. The LHCf experiment is uniquely positioned in the very forward region of the LHC to investigate the hadronic interactions relevant to high-energy cosmic ray air shower simulations by measuring forward-produced...
Electroweak Precision Measurements are stringent tests of the Standard Model and sensitive probes to New Physics. Accurate studies of the Z-boson couplings to the first-generation quarks, which are currently only constrained from LEP data, could reveal potential discrepancies from the theory predictions. Future $e^+e^-$ colliders running at the $Z$-pole would be an excellent tool for an...
The COMET experiment aims to search for the muon-to-electron $\mu-e$ conversion process, one of the lepton flavour violation processes, with a sensitivity better than $10^{-16}$ in J-PARC. To achieve this sensitivity, precisely controlling the secondary muon beam and suppressing the backgrounds is essential. The muon beam monitor will measure the muon beam profile directly, and monitor its...
A method of general applicability has been developed, whereby the null geodesic equations of the Einstein-Straus-de Sitter metric can be integrated simultaneously in terms of the curvature constant k. The purpose is to generalize the computation of light deflection and time delay by a spherical mass distribution. Assuming a flat Universe with most recent measurements of the Hubble constant H₀...
Recent results on global EFT fits of the CMS data are presented, with particular focus on the electroweak sector of the Standard Model.
We study the sensitivity of COHERENT-like experiments to non-standard contributions within the so-called $\nu$WEFT framework. The latter is the most general low-energy effective field theory that includes not only the light SM fields but also additional right-handed Dirac neutrinos.
Our analysis uses the framework presented at ["Consistent QFT description of non-standard neutrino...
Neutrino tagging is a new experimental approach for accelerator based neutrino experiments. The method consists in associating a neutrino interaction with the meson decay (i.e. $\pi^\pm\to\mu^\pm \nu_\mu$ or $K^\pm\to\mu^\pm \nu_\mu$) in which the neutrino was originally produced. The properties of the neutrino can then be estimated kinematically from the decay incoming and outgoing charged...
Probing the non-perturbative regime of Quantum Chromodynamics (QCD) remains a critical challenge in hadron spectroscopy, particularly concerning the role of gluonic excitations in shaping the hadronic spectrum. The GlueX experiment at Jefferson Lab is designed to address this challenge through the search for exotic hybrid mesons, states predicted by QCD to include gluonic degrees of freedom...
In this talk, I will present our recent developments in MadGraph5_aMC@NLO for elementary-particle production in asymmetric systems, including photoproduction and proton–nucleus collisions. I will also discuss the first implementation of bound-state production, specifically quarkonia, the simplest bound states in QCD. Indeed, we have extended the support of radiative corrections at...
We discuss factorization of jet cross sections in heavy-ion collisions. First, using Glauber modelling of heavy nuclei, a factorized formula for jet cross sections is derived, which involves defining a virtuality-dependent jet functions in QCD medium. Then, we generalize the BDMPS-Z formalism to evaluate the jet function initiated by a parton with virtuality $m_I^2$. At the end, we disucss the...
Outreach activities carried out by Research Institutions and Universities play a key role in bringing the public closer to scientific culture, and particularly, when aimed at younger audiences, in encouraging inspirations for STEM careers. In this context, numerous studies have highlighted that the most effective initiatives are those that allow students to immerse in the research setting and...
Accurately computing the decay rate of metastable vacua in quantum field theory hinges on a precise evaluation of functional determinants arising from quantum fluctuations. In this presentation, we explore recent advances in the regularisation and evaluation of these determinants. The first part introduces a streamlined method to regularize functional determinants for fields of spin 0, 1/2,...
One of the great open questions in modern physics is the origin of the matter-antimatter asymmetry. This requires baryon-number violation, which has never been experimentally observed. Baryon-number violation may arise in the neutron sector as the direct conversion between neutrons and antineutrons, or with a sterile/mirror neutron.
This process will be probed with the proposed HIBEAM/NNBAR...
We derive a family of generalized dispersion relations with new integration kernels, and use them to bootstrap the amplitudes with full unitarity and analyticity systematically employed. These dispersion relations, combined with the primal construction method, can be used to analyze the interplay between the Regge behavior of amplitudes and low-energy scattering data. As an illustrating...
Gravitational and Structural Modifications of Compact Objects due to Quadrupole Moments in General Relativity
This study investigates the gravitational behavior of compact astrophysical objects, specifically white dwarfs and neutron stars, within Einstein’s General Relativity framework. We incorporate the quadrupole moment in a first-order approximation to analyze how deviations from...
Parton distribution functions (PDFs) describe universal properties of hadrons. They provide insights into the non-perturbative internal structure of bound states and are highly significant for experiments. Calculating PDFs involves evaluating matrix elements with a Wilson line in a light-cone direction. This poses significant challenges for Monte Carlo methods in Euclidean formulation of...
Recent measurements of the anomalous magnetic moment of the muon have challenged the Standard Model, producing significant tensions between theory and experiment. Accurate theoretical predictions are difficult due to the strongly interacting nature of QCD, which is the primary source of uncertainty in the Standard Model prediction for the muon g-2. In this talk, we present a lattice QCD...
In complex particle physics analyses where signal and background events are intertwined across multidimensional phase space, statistically consistent event-by-event weighting is indispensable for unbiased extraction of signal observables. However, many widely used methods can often fail to correctly estimate this separation, particularly in the presence of statistically independent variables...
We calculate several types of commutators associated with the leptonic Yukawa coupling matrices in the canonical seesaw mechanism, which can be used to measure leptonic CP violation in both heavy Majorana neutrino decays and light Majorana neutrino oscillations in the flavor basis. The corresponding Jarlskog-like invariants of CP violation and their small non-unitarity effects are derived...
The Pierre Auger Collaboration has performed a dedicated search for upward-going air showers using the Fluorescence Detector (FD), motivated by the two "anomalous" radio pulses reported by the ANITA experiment that are difficult to reconcile with expectations from the Standard Model. While ultrahigh-energy (UHE) neutrinos can traverse the Earth and initiate Earth-skimming showers interacting...
The Koba-Nielsen-Olesen (KNO) scaling of hadron multiplicity distributions, empirically confirmed to hold approximately in $e^+e^-$ collisions and Deep Inelastic Scattering, has been observed to be violated in hadron-hadron collisions. In this work, we show that the universality of KNO scaling can be extended to hadron-hadron collisions when restricted to QCD jets. We present a comprehensive...
While perturbative methods have led to significant insights into fundamental interactions,non-perturbative phenomena remain poorly understood—particularly in regimes where Monte Carlo (MC) techniques suffer from the sign problem, such as in dense nuclear matter and real-time dynamics in Quantum Chromodynamics (QCD). Tensor Network (TN) methods, which are not affected by the sign...
Positivity bounds in effective field theories (EFTs) can be extracted through the moment problem approach, utilizing well-established results from the mathematical literature. We generalize this formalism using the matrix moment approach to derive positivity bounds for theories with multiple field components. The sufficient conditions for
obtaining optimal bounds are identified and applied to...
Measurements of photon-induced processes are presented, using data collected in Run-2.
A long time operation of Multi-Gap Resistive Plate Chambers with gas mixtures based on C$_2$H$_2$F$_4$ and SF$_6$ leads to aging effects reflected in an increase of the dark current and dark counting rate, with impact on the chamber performance. Moreover, the higher noise rate leads to an artificial increase of the data volume in a free-streaming data acquisition operation used in high...
While the development of machine learning models for analyzing physical processes—such as simulations, reconstruction, and triggers—has progressed rapidly, efficient inference remains a major challenge. Despite the availability of popular frameworks like TensorFlow and PyTorch for model development, training, and evaluation, experiments at CERN face difficulties during inference due to issues...
Neural Simulation-Based Inference (NSBI) is a powerful class of machine learning (ML)-based methods for statistical inference that naturally handle high dimensional parameter estimation without the need to bin data into low-dimensional summary histograms. Such methods are promising for a range of measurements at the Large Hadron Collider, where no single observable may be optimal to scan over...
The planned Electron Ion Collider will be a unique, high-luminosity, high-precision accelerator to yield collisions of electrons and protons/nuclei. The ePIC experiment will be the first general-purpose detector planned for EIC. It will cover a wide area in $x - Q^{2}$ plane at different center of mass energies. Low-$x$ physics are going to be central to the EIC mission of probing gluon...
The determination of the QCD coupling, $\alpha_s$, from the analysis of inclusive hadronic tau decays is one of the most precise extractions of this fundamental parameter from experiment. For a long time, the analyses were based on the inclusive spectral functions determined by ALEPH and OPAL. These spectral functions rely on measurements of the dominant decay channels, but necessitated the...
Extra light scalars are still not excluded by the existing experimental constraints, provided their coupling to the SM gauge bosons is sufficiently suppressed. They could be produced at the e$^+$e$^-$ Higgs factory in a scalar-strahlug process, analogous to the Higgs-strahlung process being the dominant production channel for the 125 GeV Higgs boson. This was selected as one of the focus...
We study the quantum properties of the Higgs-boson decays into four fermions via two vector bosons $(H\to VV^*\to 4f)$. In particular, we focus on the case of two different-flavour lepton pairs $(H\to ZZ^*\to \mu^+\mu^- e^+ e^-)$. We compute the quantum-information observables for the corresponding two-qutrit system $(ZZ)$ at next-to-leading order electroweak (NLO EW) accuracy in the SM. We...
I will present our novel study of quarkonium-production at ultra-high transverse momentum at the LHC. We have performed a complete computation at NLO $(\alpha_s^3)$+ NLL $(\alpha_s^{n+1} \ln^n(p_T/m_H))$ using leading-power Fragmentation Functions (FFs). We have performed a thorough analysis of the theoretical uncertainties including those from the FF modelling, the scales...
We examine the rare $B_c \to D_s \ell^+ \ell^-$ decay channel mediated by the flavor changing neutral current $b \to s \ell^+ \ell^-$ transition within the $U_1$ leptoquark framework. The leptoquark couplings are taken to be complex, thus allowing for possible new CP violation sources. With a large new weak phase, a sizeable CP asymmetry may be possible. The new physics couplings are...
Rare radiative-and-leptonic $B_s$-meson decay is a golden channel to scrutinize hypothetical New Physics (NP) effects in $b \to s$ quark transitions. Contrarily to the purely leptonic counterpart, i.e. $B_s \to \mu^+ \mu^-$, it is sensitive to a larger set of Wilson coefficients and it is not helicity suppressed. The LHCb Collaboration has set a first limit on the Branching Ratio (BR) of...
Measurements of heavy baryon production in pp, pA and AA collisions from RHIC to top LHC energies have recently attracted more and more attention, currently representing a challenge for the heavy-quark hadronization theoretical understanding. In such experiments there have been many indications of the formation of a deconfined phase of quarks and gluons called the quark-gluon-plasma (QGP)....
We investigate the renormalization group scale and scheme dependence of the $H \rightarrow gg$ decay rate at the order N$^4$LO in renormalization-group summed perturbative theory, which employs the summation of all renormalization-group accessible logarithms including the leading and subsequent four sub-leading logarithmic contributions to the full perturbative series expansion. The...
Modern experiments in particle, astroparticle physics, and cosmology, particularly those probing for New Physics, are increasingly relying on quantum sensors to achieve unprecedented sensitivities.

Its setup includes a veto system, a tungsten target...
The Pierre Auger Observatory, the largest air-shower experiment in the world designed to investigate ultra-high-energy (UHE, E $\gtrsim10^{17}\,$eV) cosmic rays, offers unparalleled sensitivity to UHE photons. These are expected from interactions of UHE cosmic rays with background radiation fields, as well as from more exotic scenarios such as the decay of super-heavy dark matter (SHDM)...
Within the framework of a general non-linear effective field theory describing the electroweak symmetry breaking, we perform a detailed analysis of the next-to-leading contributions to the electroweak oblique parameters S and T from hypothetical heavy resonance states strongly coupled to Standard Model fields. This work extends our previous results by including parity-odd operators in the...
The CREDO collaboration studies cosmic-ray related phenomena on a large scale, searching for so called Cosmic-Ray Ensembles (CRE) and other unusual correlations and anomalies of non local nature. Such studies require data on Extensive Air Showers (EAS) and flux of secondary cosmic-ray particles that covers large areas. To perform such measurements, a large network of inexpensive detectors...
Despite the large amount of data generated by the Large Hadron Collider (LHC) so far, searches for new physics have not yet provided any clear evidence of beyond the Standard Model (BSM) physics. Most of these experimental searches focus on exclusive channels, looking for excesses in specific final states. However, new physics could manifest as a dispersed signal over many channels. It...
We present a discussion of model-independent contributions to the EDM of the electron.
We focus on those contributions that can emerge from an extended heavy scalar sector, and in particular we explore the decoupling limit of the aligned 2HDM.
In this model, Barr-Zee diagrams with a fermion loop produce logarithmically-enchanced contributions that are proportional to potentially large...
The Electric Dipole Moment of the electron (eEDM) is typically investigated in experiments using paramagnetic molecules. However, the physical observable in these searches consists of a linear combination of CP-violating interactions, rather than the eEDM alone, which is commonly referred to as the equivalent EDM of the system. Assuming the presence of new CP-odd physics from heavy degrees of...
ESSnuSB is a design study for a long-baseline neutrino experiment to precisely measure the CP violation in the lepton sector at the second neutrino oscillation maximum, using a beam driven by the uniquely powerful ESS linear accelerator.

The matrix model for the two-color QCD coupled to a single quark (matrix-QCD$_{2,1}$) exhibits novel features, such as the Pauli-G\"{u}rsey symmetry. Using variational methods, we numerically investigate matrix-QCD$_{2,1}$ in the limit of ultra-strong Yang-Mills coupling ($g_{YM} =\infty$). The spectrum of the model has superselection sectors labelled by baryon number $B$ and spin $J$. We...

The virtual corrections for $gg \to HH$ at NLO QCD have been efficiently approximated using a Taylor expansion in the limit of a forward kinematics. The same method has been recently applied to the calculation of a subset of the NNLO corrections, which are desirable given the significant impact, at NLO, of the uncertainty due to the choice of the top mass renormalization scheme. In this talk,...
Identifying products of ultrarelativistic collisions delivered by the LHC and RHIC colliders is one of the crucial objectives of experiments such as ALICE and STAR, which are specifically designed for this task. They allow for a precise Particle Identification (PID) over a broad momentum range.
Traditionally, PID methods rely on hand-crafted selections, which compare the recorded signal of...
We explore the prospects of exclusive $W^+W^-$ production via
photon-photon fusion at the LHeC, operating at a center-of-mass energy
of 1.2 TeV [1]. Utilizing the clean experimental environment and high
luminosity of the LHeC [2,3], this process could provide a powerful
probe of electroweak interactions and possible deviations from SM,
particularly through anomalous quartic gauge...
AI nowadays is a new tool that seems to be everywhere including education. It brings convenience but also concerns - the two largest concerns with using AI by instructors are the safety of students’ data and the AI lack of the specific knowledge needed in a specific class. The data safety can be addressed by using a locally run large language models model using Ollama framework, a free tool...
