Neutrino results from the FASER experiment / Boyd, Jamie (CERN) /FASER Collaboration
The FASER experiment at the LHC is designed to search for light, weakly-coupled new particles, and to study high-energy neutrinos. The experiment has been running since 2022, and has collected nearly 200 fb$^{-1}$ of $pp$ collision data. [...]

First results from FASER at the LHC / Hayakawa, Daiki (Chiba U.) /FASER Collaboration
The ForwArd Search ExpeRiment (FASER) is a new experiment at the Large Hadron Collider (LHC) designed to search for light, weakly-interacting particles. Placed 480 m downstream from the ATLAS interaction point along the beam collision axis, FASER detects particles that travel hundreds of meters. [...]

FASER experiment and first results from LHC run 3 / Kose, Umut (ETH, Zurich) /Umut Kose Collaboration ; FASER Collaboration
FASER is designed to search for light, extremely weakly interacting and long-lived beyond standard model particles at the CERN Large Hadron Collider. Such particles, e.g., dark photons, may be produced in the high-energy proton-proton collisions at the ATLAS interaction point and then decay to visible particles in FASER, which is placed 480 m downstream and aligned with the collision axis line-of-sight. [...]

Latest neutrino results from the FASER experiment and their implications for forward hadron production /FASER collaboration
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 forward particle production in hadronic interactions is not fully understood. [...]

FASER tracker performance / Xu, Yue (U. Washington, Seattle (main)) /FASER Collaboration
FASER is located 480 meters from the ATLAS interaction point, along the collision axis. The tracking system of the FASER detector consists of four identical tracker stations made from silicon microstrip detectors. [...]

The W-Si High Precision Preshower Detector of the FASER Experiment at the LHC / Hayakawa, Daiki (Chiba U.) /FASER Collaboration
FASER is searching for light, weakly-interacting particles at the Large Hadron Collider. The first search for Axion-like particles (ALPs) decaying to a photon pair using data collected in 2022 and 2023 was performed and successfully excluded regions not previously ruled out. [...]

Neutrinos at the LHC - Results from FASER / Atkinson, Jeremy (U. Bern, AEC) /FASER Collaboration
The goal of FASER, the ForwArd Search ExpeRiment, at the CERN LHC, is to investigate light, weakly-interacting particles. Aligned with the collision axis line-of-sight of the ATLAS interaction point, it is located 480 m downstream, and covers the previously unexplored pseudorapidity range of 𝜂 > 8.8. [...]

New Physics Results from the FASER Experiment / Macdonald, Jack (Mainz U.) /FASER Collaboration
FASER, the ForwArd Search ExpeRiment, has successfully taken data at the LHC since the start of Run 3 in 2022. From its unique location along the beam collision axis 480 m from the ATLAS interaction point, FASER has world-leading sensitivity to many models of long-lived particles. [...]
