| contents | We present the latest physics results from the FASER experiment at the LHC. Using $pp$ collision data at $\sqrt{s} = 13.6$ TeV collected during LHC Run 3, FASER reports new results on four fronts: a search for dark photons with an improved analysis strategy using $177~fb^{-1}$ 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 FASER$ν$ emulsion detector with a 681 kg tungsten target and $9.5~fb^{-1}$ of 2022 data; the first observation of $ν_e$ in the FASER electronic detector at $5.5σ$ using $176.8~fb^{-1}$ of data; and the first double-differential measurement of $ν_μ$ interactions as a function of energy and rapidity with $186~fb^{-1}$ of data. |
