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…
Spin Correlations in Dark Photon Searches
Jonathan L. Feng, MiÅ¡a Toman, Miša Toman +1
We investigate the spin correlations between production and decay in the process where dark photons are produced in pseudoscalar meson decays, for example, , an…
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…
Prospects and Opportunities with an upgraded FASER Neutrino Detector during the HL-LHC era: Input to the EPPSU
FASER Collaboration, Roshan Mammen Abraham, Xiaocong Ai +115
The FASER experiment at CERN has opened a new window in collider neutrino physics by detecting TeV-energy neutrinos produced in the forward direction at the LHC. Building on this s…
