The BRAND experiment aims at the search of Beyond Standard Model (BSM) physics via measurement of exotic components of the weak interaction. For this purpose, eleven correlation coefficients of neutron beta decay will be measured simultaneously. Seven of them: H, L, N, R, S, U, and V, are sensitive to the transverse polarization of electrons from free neutron decay. Coefficients: H, L, S, U,...
The Mu2e experiment at Fermilab will search for the Standard Model forbidden coherent conversion of a negative muon into an electron
in the field of an aluminum nucleus.
The calorimeter complements the tracking information, providing track-seeding and particle identification to help reconstruct the mono-energetic electron candidates. The calorimeter is based on 1348 undoped CsI crystals...
The LUXE experiment aims at studying high-field QED in electron-laser and photon-laser interactions, with the 16.5 GeV electron beam of the European XFEL and a laser beam with power of up to 350 TW. The experiment will measure the spectra of electrons, positrons and photons in expected ranges of 10^-3 to 10^9 per 1 Hz bunch crossing, depending on the laser power and focus. These measurements...
In the High Luminosity era, the Large Hadron Collider (LHC) will be upgraded to deliver instantaneous luminosities up to $5 \times 10^{34} \ \mathrm{cm^{-2}s^{-1}}$, five times more than the original design value. In order to maintain performance of the Compact Muon Solenoid (CMS) experiment under these conditions, ME0 is one of the three new muon sub-detectors being added, along with GE1/1...
Magnetic and electric dipole moments of fundamental particles provide powerful probes for physics within and beyond the Standard Model. For the case of short-lived particles, these have not been experimentally accessible to date due to the difficulties imposed by their short lifetimes. The R&D on bent crystals and the experimental techniques developed to enable such measurements are discussed....
With its increased number of proton-proton collisions per bunch crossing, track
reconstruction at the High-Luminosity LHC (HL-LHC) is a complex endeavor. The Inner
Tracker (ITk) is a silicon-only replacement of the current ATLAS tracking system as part of
its Phase-II upgrade.
It is specifically designed to handle the challenging conditions resulting from the increase
in...
FASER, or the Forward Search Experiment, is a new experiment at CERN designed to complement the LHC's ongoing physics program, extending its discovery potential to light and weakly-interacting particles that may be produced copiously at the LHC in the far-forward region. New particles targeted by FASER, such as long-lived dark photons or dark scalars, are characterized by a signature with two...
Lepton beam facilities at intensity frontiers open new opportunities for precision and BSM physics. Jefferson Lab currently hosts the CEBAF accelerator which delivers a 12 GeV high power electron beam (up to 1 MW) to run in parallel up to four fixed target experiments. The comprehensive physics program includes: nucleon and nuclear structure, hadron spectroscopy and physics beyond the SM....
The tracking performance of the ATLAS detector relies critically on its 4-layer
Pixel Detector. As the closest detector component to the interaction point, this detector is subjected to a significant amount of radiation over its lifetime. By the end of the LHC proton-proton collision RUN2 in 2018, the innermost layer IBL, consisting of planar and 3D pixel sensors, had received an integrated...
For the Phase 2 upgrade, the CMS experiment foresees the installation of a MIP Timing Detector (MTD) to assign a precise timestamp to every charged particle up to pseudorapidity |$\eta$| = 3, empowering the CMS detector with unique and new capabilities. The target timing resolution of MTD, 40 ps per track, will help reduce the challenging pile-up conditions expected at the High-Luminosity LHC...
In the frame of the progress towards the High Luminosity Program of the Large Hadron Collider at CERN, the ATLAS and CMS experiments are boosting the preparation of their new environmental friendly low temperature detector cooling systems. This paper will present a general overview of the progress in development and construction of the future CO2 cooling systems for silicon detectors at ATLAS...
The CMS silicon strip tracker with its more than 15000 silicon modules and 200m2 of active silicon area will resume operation after 3 years of Long Shutdown 2 in the Spring of 2022. We present the status of the detector before the start of the LHC Run 3 data taking. The performance of the detector during the Run 2 data taking is presented including the signal-to-noise ratio, fraction of bad...
After ten years of intense work, the two New Small Wheels (NSW) for the upgrade of the Atlas Muon Spectrometer are now installed in the experiment and ready for final commissioning and to collect data in LHC Run3, starting March 2022.
The NSW is the largest phase-1 upgrade project of ATLAS. Its challenging completion and readiness for data taking is a remarkable achievement of the...
The Electromagnetic Calorimeter (ECAL) barrel of CMS experiment at CERN is made of 36 Supermodules, each consisting of 1700 lead tungstate scintillating crystals. Each Supermodule weighs 2.7 tonnes and is a highly sensitive and fragile object. The Supermodules, 18 Supermodules on each side of CMS barrel, were successfully inserted inside the Hadronic Calorimeter (HCAL) barrel of CMS in 2007...
The MoEDAL Apparatus for Penetrating Particles (MAPP) was recently approved by CERN's Research Board to take data during LHC's Run-3. This detector extends the physics reach of the MoEDAL detector, the LHC's first dedicated search experiment that was built to detect highly ionizing avatars of new physics. The MAPP detector will concentrate on the search for feebly (electromagnetically)...
At the Mainz Microtron MAMI, the technique of high-resolution spectroscopy of decay-pions in strangeness electroproduction has been established to extract $\Lambda$ ground state binding energies of light hyperfragments. In a first series of measurements, a $^9$Be target was used to determine the $^4_\Lambda$H binding energy with unprecedented precision in a momentum setting near 133 MeV/c. The...
FASER is a new experiment designed to search for new light weakly-interacting long-lived particles (LLPs) and study high-energy neutrino interactions in the very forward region of the LHC collisions at CERN. The experimental apparatus is situated 480~m downstream of the ATLAS interaction-point aligned with the beam collision axis. The FASER detector includes four identical tracker stations...
Throughout ATLAS Run-2, the LUCID detector, that is located close to the beampipe on both side of the interaction point, has been the reference luminosity detector, providing the online and offline luminosity measurement with high stability and a preliminary uncertainty of about 1.7%.
For the high-luminosity LHC, new beampipe equipment and more demanding luminosity precision requirements and...
The full optimization of the design and operation of instruments whose functioning relies on the interaction of radiation with matter is a super-human task, given the large dimensionality of the space of possible choices for geometry, detection technology, materials, and data-acquisition and information-extraction techniques, and the interdependence of the related parameters. On the other...
