Abstract

We present the latest physics results from the FASER experiment at the LHC. Using pppp collision data at s=13.6\sqrt{s} = 13.6 TeV collected during LHC Run 3, FASER reports new results on four fronts: a search for dark photons with an improved analysis strategy using 177 fb1177~fb^{-1} of data, yielding world-leading exclusion limits; neutrino cross section measurements and the first search for charm hadron production in neutrino interactions, both using the FASERν\nu emulsion detector with a 681 kg tungsten target and 9.5 fb19.5~fb^{-1} of 2022 data; the first observation of νe\nu_e in the FASER electronic detector at 5.5σ5.5\sigma using 176.8 fb1176.8~fb^{-1} of data; and the first double-differential measurement of νμ\nu_\mu interactions as a function of energy and rapidity with 186 fb1186~fb^{-1} of data.
