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 …
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 Direct Observation of Collider Neutrinos with FASER at the LHC
FASER Collaboration, Henso Abreu, John Anders +85
We report the first direct observation of neutrino interactions at a particle collider experiment. Neutrino candidate events are identified in a 13.6 TeV center-of-mass energy …
Neutrino Rate Predictions for FASER
FASER Collaboration, Roshan Mammen Abraham, John Anders +97
The Forward Search Experiment (FASER) at CERN's Large Hadron Collider (LHC) has recently directly detected the first collider neutrinos. Neutrinos play an important role in all FAS…
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…
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…
First Measurement of the and Interaction Cross Sections at the LHC with FASER's Emulsion Detector
FASER Collaboration, Roshan Mammen Abraham, John Anders +102
This paper presents the first results of the study of high-energy electron and muon neutrino charged-current interactions in the FASER emulsion/tungsten detector of the FASER e…
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…
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…
