Title: FASER’s Search for Dark Photons and Neutrinos
Abstract: FASER is an experiment at the LHC that is designed to search for light, weakly-interacting particles produced in the far-forward direction from proton-proton collisions at the ATLAS interaction point (IP1). The detector is positioned 480 m downstream of IP1 and aligned with the beam collision axis, where particles must traverse LHC magnets and approximately 100 m of rock and concrete before reaching FASER. The novel location of the experiment provides both a low background environment and a high-intensity flux of long-lived particles. This talk will provide an overview of the FASER detector and present our first physics results, where we used a dataset collected at center-of-mass energy √s =13.6 TeV in 2022, during LHC Run 3, to directly observe neutrino interactions at a particle collider experiment for the first time and also to probe previously unconstrained phase space of the dark photon with couplings ϵ∼10−5−10−4 and masses ∼10 MeV – 100 MeV.
