FASER (ForwArd Search Experiment), located 480 meters downstream of ATLAS and operational since the start of LHC Run 3, has opened a new window into collider neutrino physics, marking “the dawn of collider neutrino physics”. It is exploring previously uncharted territory in the forward region of pp collisions at the LHC. FASER has a dual mission: detecting high energy neutrinos, and searching for light, extremely weakly interacting, long lived particles predicted by various extensions of the Standard Model. In this talk, I will focus on the neutrino program of FASER. I will present the scientific motivations for detecting collider neutrinos and highlight the recent breakthrough results obtained by FASER during LHC Run 3. Finally, I will outline our proposed upgrades and experimental strategy for LHC Run 4, aimed at significantly enhancing sensitivity to neutrino flavor physics and rare processes. I will also briefly introduce the proposed Forward Physics Facility at the High Luminosity LHC, which would extend these studies even further.
