The Large Hadron electron Collider (LHeC) is the proposal to deliver electron-proton/nucleus collisions at CERN using the LHC hadron or nuclear beams and a 50 GeV electron beam from an Energy Recovery Linac (ERL) in racetrack configuration. While the 2021 update of its CDR [1] contemplated concurrent operation of electron-hadron and hadron-hadron collisions at the HL-LHC followed by standalone...
The LUXE experiment will study laser electron scattering at the European XFEL at DESY to explore an uncharted domain in Quantum Electrodynamics. To measure the number and the energy spectrum of electrons and positrons, produced in the multi-photon Breit-Wheeler process over a wide range of multiplicity, two electromagnetic calorimeters are foreseen. In Monte Carlo simulations it was...
The design of tracking chambers for future e⁺e⁻ colliders presents several challenges in terms of achieving high precision while maintaining low material budget and efficient particle identification. This presentation focuses on the development of a novel helium-based drift chamber for the IDEA (Innovative Detector for an Electron-positron Accelerator) experiment. The chamber, featuring a 4 m...
For precise and unbiased physics analyses it is crucial that all the physics object have energy scales and resolution measured in data well described by Monte Carlo Simulations. In this talk we present the methods used to measure energy scale and resolutions for muons in CMS using Run3 data. The impact of these corrections on physics results is also assessed.
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...
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 investigation of two-neutrino and neutrino-less double beta decay is crucial for understanding the Dirac or Majorana nature of neutrinos.
In this context, the krypton isotope Kr-78 (Q=2.88 MeV) stands out as a promising candidate for a first detection of two-neutrino ECb+ and 2b+ decays.
Detectors like the proposed NuDoubt++ experiment featuring opaque scintillator or an upgrade of...
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...
Physical processes with one or more τ-lepton in the final state play an important role in several analyses of the ATLAS experiment physics program. The usage of hadronic channels, in which τ-leptons decay into one or more pions, enables to exploit the large statistics associated with hadronic τ-lepton decays, but also requires a precise estimate of a sizable background of hadronic jets...
New detector concepts are necessary in order to uncover the physics Beyond the Standard Model. As the need for optimal detector performance increases, ensuring the best Quality Control (QC) for the new components is more important than ever. Among the aspects of detector QC, the Visual Inspection of components is a major procedure both in term of time and complexity. This is especially the...
T2K (Tokai to Kamioka) is a long-baseline neutrino oscillation experiment that has taken data since 2010. After having obtained the first hints of CP violation in the leptonic sector, it has entered a second phase with an upgrade of its accelerator beam line and suite of near detectors. Among the different elements of this upgrade, two High-Angle Time Projection Chambers (HA-TPC) were...
During nominal LHC collisions, protons can interact with residual gas in the beam pipe or with upstream collimators, producing showers of background particles known as Beam-Induced Backgrounds (BIB). These particles do not originate from the actual proton-proton interaction point. BIB can significantly impact detector performance and mimic signals in searches for missing energy or for certain...
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...
In 2024 the Belle II experiment resumed data taking after its Long Shutdown 1, which was required to install a two-layer pixel detector and upgrade components of the accelerator. We describe the challenges of this upgrade and report on the operational experience during the subsequent data taking. With new data, the SVD confirmed high hit efficiency, large signal-to-noise and good...
Progresses towards a Silicon-Tungsten ECAL for Higgs Factory Detectors
One way to achieve instrumental precision at future Higgs factories,
where multi-jets events represent the majority of the final states, is to conceive detectors based on the Particle Flow approach. This is the assumption followed by ILD(LC), SiD, CLICdet, ILD(CC), CLD and the baseline detectors concepts for the ILC,...
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...
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...
The LHCb detector has undergone a significant upgrade, enabling the experiment to acquire data with an all-software trigger, made possible by real-time front-end readout and fast, efficient online reconstruction. The Upstream Tracker (UT), a four-plane silicon microstrip detector located in front of the dipole magnet, is crucial for charged particle trajectory reconstruction. The UT is...
Wavelength-shifting optical fibers are commonly used to collect light from large detector volumes and guide towards photosensors, making them particularly interesting for water Cherenkov or scintillator based detectors. However, one problem is their low photon capture rate, leading to a degradation in the energy resolution of fiber-based detectors.
Building on previous work, it was shown...
