The trigger and data acquisition system of the FASER experiment

FASER Collaboration, Henso Abreu, Elham Amin Mansour +81

The FASER experiment is a new small and inexpensive experiment that is placed 480 meters downstream of the ATLAS experiment at the CERN LHC. FASER is designed to capture decays of…

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

The FASER Detector

FASER Collaboration, Henso Abreu, Elham Amin Mansour +94

FASER, the ForwArd Search ExpeRiment, is an experiment dedicated to searching for light, extremely weakly-interacting particles at CERN's Large Hadron Collider (LHC). Such particle…

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

The tracking detector of the FASER experiment

FASER Collaboration, Henso Abreu, Claire Antel +77

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…

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…

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…
