Article Citation - Scopus: 2Observation of Collider Neutrinos without Final State Muons with the SND at LHC Experiment(American Physical Society, 2025) Abbaneo, D.; Ahmad, S.; Albanese, R.; Alexandrov, A.; Alicante, F.; Androsov, K.; Zamora-Saá, J.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 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. © 2025 authors. Published by the American Physical Society.
