Abstract: FASER, the ForwArd Search ExpeRiment, is an LHC experiment located 480 m downstream of the ATLAS interaction point along the beam collision axis. FASER and its sub-detector, FASERν, have two primary physics goals: (1) to detect and study TeV-energy neutrinos—the most energetic neutrinos ever observed from a human-made source—and (2) to search for new, light, and feebly interacting particles. FASER is designed, constructed, installed, and commissioned between 2019 and 2022, and it has been collecting physics data since the start of LHC Run 3 in July 2022. So far, we have collected data from 190 fb⁻¹ of proton-proton collisions at a center-of-mass energy of 13.6 TeV. This talk will present the current status of the experiment, including the detector design and the first detector performance results based on Run 3 data.
