Electromagnetic Shower Reconstruction and Identification in FASER's Emulsion Detector for LHC Forward Neutrino Measurements
FASER Collaboration, Roshan Mammen Abraham, Xiaocong Ai +137
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…
Optimization of muon suppression using sweeper magnets for the Forward Physics Facility at the HL-LHC
Akitaka Ariga, Tomoko Ariga, Jeremy Atkinson +13
The Forward Physics Facility (FPF) at the High-Luminosity LHC (HL-LHC) will enable high-statistics measurements of TeV-scale neutrinos, but the intense flux of forward muons poses…
Momentum Measurement of Charged Particles in FASER's Emulsion Detector at the LHC
FASER Collaboration, Roshan Mammen Abraham, Xiaocong Ai +132
We present a momentum measurement method based on multiple Coulomb scattering (MCS) in the FASER emulsion detector. The measurement of charged-particle momenta is essential for…
Latest neutrino results from the FASER experiment and their implications for forward hadron production
FASER Collaboration, Roshan Mammen Abraham, Xiaocong Ai +117
The muon puzzle -- an excess of muons relative to simulation predictions in ultra-high-energy cosmic-ray air showers -- has been reported by many experiments. This suggests that fo…
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…
Reconstruction and Performance Evaluation of FASER's Emulsion Detector at the LHC
FASER Collaboration, Roshan Mammen Abraham, Xiaocong Ai +121
This paper presents the reconstruction and performance evaluation of the FASER emulsion detector, which aims to measure interactions from neutrinos produced in the forward dire…
