New physics has traditionally been expected in the high-$p_T$ region at high-energy collider experiments. If new particles are light and weakly-coupled, however, this focus may be completely misguided: typically highly concentrated within a few mrad of beam line, allowing sensitive searches with small detectors, even extremely weakly-coupled produced large numbers there. We propose experiment, ForwArd Search ExpeRiment, or FASER, which would placed downstream ATLAS CMS interaction point (IP)...
FASER,the ForwArd Search ExpeRiment,is a proposed experiment dedicated to searching for light, extremely weakly-interacting particles at the LHC. Such may be produced in LHC's high-energy collisions and travel long distances through concrete rock without interacting. They then decay visible FASER, which is placed 480 m downstream of ATLAS interaction point. In this work we briefly describe FASER detector layout status potential backgrounds. We present sensitivity reach large number...

Abstract Neutrinos are copiously produced at particle colliders, but no collider neutrino has ever been detected. Colliders produce both neutrinos and anti-neutrinos of all flavors very high energies, they therefore highly complementary to those from other sources.

Visible signals from the decays of light long-lived hidden sector particles have been extensively searched for at beam dump, fixed-target, and collider experiments. If such sectors couple to Standard Model through mediators heavier than $\sim 10$ GeV, their production low-energy accelerators is kinematically suppressed, leaving open significant pockets viable parameter space. We investigate this scenario in models inelastic dark matter, which give rise visible various existing proposed LHC...
