Abstract

The ICARUS Collaboration is now entering its sixth year of continuing operations of the 760-ton liquid argon T600 detector. The T600 was overhauled at CERN after operations at the LNGS underground laboratory in Italy and moved to its present location at FNAL—as part of the Short-Baseline Neutrino (SBN) program—where it completed its commissioning phase in June 2022. At FNAL, ICARUS collects neutrino interactions from both the Booster Neutrino Beam (BNB) and off-axis from the Neutrinos at Main Injector beam (NuMI). ICARUS has accumulated approximately 10.6×1020 protons on target (POT) with the BNB and about 6.2×1020 POT with NuMI. Within the SBN program, ICARUS will search for evidence of short-baseline oscillations, potentially explained by eV-scale sterile neutrinos, jointly with the Short-Baseline Near Detector (SBND). In addition, ICARUS is performing stand-alone oscillation searches in disappearance mode and measuring neutrino cross sections on argon with both the BNB and NuMI beams. It is also performing searches for additional Beyond the Standard Model signatures. This paper describes the analysis status as shown at ICNFP 2025.
