ForwArd Search ExpeRiment at the LHC, a.k.a. FASER, is a novel approach to exploit proton-proton collisions for discovery of weakly coupling light long-lived dark sector particles in the phase-space to which no current experiment has access and also make the first 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. This talk will present FASER’s physics prospects, current status, and commissioning progress using collision data from Run 3 delivered by the LHC since May 2022. This talk will also discuss upgrade of the detector, and new idea about FASER2 & a future Forward Physics Facility to further exploit forward production in LHC collisions.
