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...

The Forward Search Experiment (FASER) at CERN’s Large Hadron Collider (LHC) has recently directly detected the first collider neutrinos. Neutrinos play an important role in all FASER analyses, either as signal or background, and it is therefore essential to understand neutrino event rates.
