FASER, the ForwArd Search ExpeRiment, is a novel approach to exploit proton-proton collisions for discovery of weakly coupling light long-lived dark sector particles in the phase-space which no current experiment has access to and collider-originated neutrino measurements at the TeV energy scale. The detector is located at the LHC in the far-forward region 480 m from the ATLAS interaction point and has been taking physics data since the start of LHC Run3 in July 2022. This talk will present FASER’s first physics results from a search for dark photons decaying to an electron-positron pair and the first direct observation of collider neutrinos. This talk will also discuss upgrade of the detector and new ideas about FASER2 and a future Forward Physics Facility to deepen understanding forward production physics in LHC collisions.
