Detecting Collider Neutrinos at the LHC: the FASER Experiment — •Wissal Filali, Florian Bernlochner, Tobias Boeckh, and Markus Prim — Physikalisches Institut der Universität Bonn

The neutrinos produced at the Large Hadron Collider (LHC) proton-proton collision provide an opportunity to explore the TeV regime which has remained largely uncharted. The FASER experiment, located 480 meters downstream from the ATLAS interaction point and aligned with the beam collision axis, aims to measure the interaction cross section and flux of neutrinos ν_mu in the energy range from 400GeV to 6TeV. Using FASER’s active electronic detector, charged current interactions of muon neutrinos and anti-neutrinos are identified, the neutrino flux is measured in six momentum bins and five pseudorapidity bins, with correlations between these measurements providing improved precision in the flux determination. In this presentation, we present the current status of the analysis.

Keywords: LHC neutrinos; pseudo-rapidity; TeV neutrinos
