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. FASER, the Forward Search Experiment LHC, is ideally located provide first detection study neutrinos. We investigate prospects for studies with FASER $$\nu $$ <mml:math...
