The search for new physics and studying the properties of the Standard Model (SM) neutrinos are among the main frontiers in contemporary particle physics. In particular, new physics searches at the Large Hadron Collider (LHC) have traditionally been performed in the high-pT region. If new particles are light and weakly-coupled, however, this focus may be misguided: light particles are typically highly concentrated within a few mrad of the beam line. This opens up a novel direction in the LHC searches focusing on sub-GeV beyond the SM species and neutrino measurements, which will be initiated by the FASER experiment during Run 3. In the talk, we will discuss the prospects of these and other related efforts that can extend towards the High-Luminosity phase of the LHC in the recently proposed Forward Physics Facility (FPF).
