How Will FASERν Transform Our Understanding of Neutrinos at High Energies?

In summary, the FASERν detector at the CERN Large Hadron Collider has successfully detected neutrino interactions for the first time at high energies, paving the way for future measurements at current and future colliders. This was achieved through a pilot detector installed in the far-forward region of ATLAS, which collected data from proton-proton collisions at 13 TeV. These results are a major milestone in the study of high-energy neutrinos at the LHC.

TL;DR Summary
Experimentalists have found a way to detect collider neutrinos and their flavor.
FASERν 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.
