Electromagnetic Shower Reconstruction and Identification in FASER's Emulsion Detector for LHC Forward Neutrino Measurements
FASER Collaboration, Roshan Mammen Abraham, Xiaocong Ai +132
We present methods for electromagnetic shower reconstruction and identification in the FASERnu emulsion detector using 100 GeV and 200 GeV electron test-beam data from the CERN SPS…
First Measurement of the Muon Neutrino Interaction Cross Section and Flux as a Function of Energy at the LHC with FASER
FASER Collaboration, Roshan Mammen Abraham, Xiaocong Ai +107
This letter presents the measurement of the energy-dependent neutrino-nucleon cross section in tungsten and the differential flux of muon neutrinos and anti-neutrinos. The analysis…
Shining Light on the Dark Sector: Search for Axion-like Particles and Other New Physics in Photonic Final States with FASER
FASER collaboration, Roshan Mammen Abraham, Xiaocong Ai +106
The first FASER search for a light, long-lived particle decaying into a pair of photons is reported. The search uses LHC proton-proton collision data at …
Testbeam Characterization of a SiGe BiCMOS Monolithic Silicon Pixel Detector with Internal Gain Layer
L. Paolozzi, M. Milanesio, T. Moretti +22
A monolithic silicon pixel ASIC prototype, produced in 2024 as part of the Horizon 2020 MONOLITH ERC Advanced project, was tested with a 120 GeV/c pion beam. The ASIC features a ma…
