Short-Baseline neutrino oscillation searches with the ICARUS detector

Abstract

The ICARUS detector represents the first large-scale example of the LAr-TPC detection technique for neutrino and rare event physics. Its underground run at LNGS (2010-13) provided important results in the search for sterile neutrinos. The Short Baseline Neutrino program at Fermilab will further address the sterile neutrino puzzle, confirming or disproving the existence of a fourth neutrino flavour in both appearance and disappearance channels. ICARUS will act as the SBN far detector, taking advantage of the excellent reconstruction capability of LAr-TPC. The ICARUS commissioning phase, culminating in the "Run 0" in June 2021, has largely been successful, confirming that ICARUS is able to take physics data continuously with high live-time. The first physics run is planned to start in October 2021.
