Abstract: Neutrinos are copiously produced at particle colliders with energies which are complementary to other sources. But until recently no collider neutrino has ever been detected. This talk presents the first measurements of the neutrino-nucleon cross section in tungsten and the differential muon neutrino flux at the LHC with FASER. I will present the recent results using the FASER emulsion and electronic detectors. The cross section measurements offer a connection between accelerator-based neutrino studies and astroparticle physics data. And the flux measurement is used to extract the contribution of neutrinos from pion and kaon decays, providing insights into the cosmic-ray muon puzzle.
