Abstract

: We report the observation of neutrino interactions without final state muons at the LHC, with a significance of 6.4σ. A dataset of proton-proton collisions at sqrt[s]=13.6  TeV collected by SND@LHC in 2022 and 2023 is used, corresponding to an integrated luminosity of 68.6  fb^{-1}. Neutrino interactions without a reconstructed muon are selected, resulting in an event sample consisting mainly of neutral-current and electron neutrino charged-current interactions in the detector. After selection cuts, 9 neutrino interaction candidate events are observed with an estimated background of 0.32 events.
