Selection of fully contained 𝜈μCC events in the ICARUS T600 detector at Fermilab

Poster presented at the XXI International Workshop on Neutrino Telescopes - Padova 29 September - 3 October 2025 (https://agenda.infn.it/event/44606/) On behalf of the ICARUS Collaboration Abstract: The ICARUS T600 LAr-TPC detector is presently taking at Fermilab within the SBN program. This detector is recording neutrino interactions from the Booster BNB neutrino beam to definitively clarify the open questions related to the possible existence of sterile neutrinos, as suggested by numerous observed experimental anomalies. In addition the neutrinos recorded from the off-axis NuMI beam are under study in order to perform neutrino-Argon cross section measurements.At Fermilab, ICARUS is installed essentially at Earth surface: for this reason cosmic ray particles can become a serious source of background for the neutrino event search. This condition makes it necessary to deploy suitable automatic tools for the identification, selection, and measurement of the neutrino events among the millions of events triggered by cosmics.In this poster, two automatic selection procedures devoted to the identification of fully contained muon neutrino CC interactions in the BNB neutrino beam will be presented, together with the first results of their application on simulated and on recently recorded events in the T600 detector.
