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 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,...
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...
SND@LHC is a compact, standalone experiment located in the TI18 tunnel, 480 meters downstream of the ATLAS interaction point, designed to observe neutrinos produced in LHC proton-proton (pp) collisions. The SND@LHC detector allows for the identification of all three flavors of neutrino interactions in the pseudorapidity region 7.2 < η < 8.4 within an unexplored energy range of 100 GeV < E < 1...
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...
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...
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 CMS experiment relies on high-precision reconstruction of particles to access a wide range of analyses. This talk presents recent developments in the reconstruction and performance of key objects using early Run 3 data. Advances include improved calibration techniques, machine learning-based identification, and improved pileup mitigation strategies.
Resistive Plate Chambers (RPCs) are particle detectors extensively used in several domains of Physics. In High Energy Physics, they are typically operated in avalanche mode with a high-performance gas mixture based on Tetrafluoroethane (C2H2F4), a fluorinated high Global Warming Potential greenhouse gas.
The RPC EcoGas@GIF++ Collaboration has pursued an intensive R&D activity to search for...
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 pursuit of high time resolution in Resistive Plate Chambers (RPCs) continues to drive innovation across fields such as particle physics and medical diagnostics. While technological improvements remain essential, it is equally important to recognize the intrinsic statistical limitations imposed by the stochastic nature of particle detection and signal formation in these detectors. This...
In order to fulfill the requirements of the high luminosity and hard radiation in HL-LHC, CMS is upgrading most of the sub detectors. In this talk, the current status of the phase-2 upgrade of CMS Inner and Outer Tracker detectors will be presented.
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...
