FASERν, located at the CERN Large Hadron Collider (LHC), is the first experiment designed to directly detect collider neutrinos and analyze their cross sections at TeV energies. The pilot detector, utilizing emulsion films, was installed in 2018 in the far-forward region of ATLAS, 480 m from the interaction point, and successfully collected 12.2 fb−1 of proton-proton collision data at a center-of-mass energy of 13 TeV. The analysis of this pilot run data has led to the observation of the first neutrino interaction candidates at the LHC, marking a significant milestone for high-energy neutrino measurements in current and future collider experiments.

https://journals.aps.org/prd/pdf/10.1103/PhysRevD.104.L091101FASERν at the CERN Large Hadron Collider (LHC) is designed to directly detect collider neutrinos for the first time and study their cross sections at TeV energies, where no such measurements currently exist. In 2018, a pilot detector employing emulsion films was installed in the far-forward region of ATLAS, 480 m from the interaction point, and collected 12.2 fb−1 of proton-proton collision data at a center-of-mass energy of 13 TeV. We describe the analysis of this pilot run data and the observation of the first neutrino interaction candidates at the LHC. This milestone paves the way for high-energy neutrino measurements at current and future colliders.
