Short-Baseline neutrino oscillation searches with the ICARUS detector.

The ICARUS Collaboration employed the 760-ton T600 detector in a successful three-year physics run at the underground LNGS laboratories, performing a sensitive search for LSND-like anomalous $\nu e$ appearance in the CNGS beam. After a significant overhaul at CERN, the T600 detector was installed at Fermilab and in 2020 the cryogenic commissioning began. ICARUS has then started operations and is presently in its commissioning phase, collecting the first neutrino events from the Booster Neutrino Beam and the NuMI off-axis. The main goal of the first year of ICARUS data taking will be the definitive verification of the recent claim by NEUTRINO-4 short baseline reactor experiment. After the first year of operations, ICARUS will search for evidence of a sterile neutrino jointly with the SBND near detector. The ICARUS exposure to the NuMI beam will also give the possibility for other physics studies such as light dark matter searches and neutrino-argon cross-section measurements. The proposed contribution will address ICARUS achievements, its status and plans for the new run at Fermilab and the ongoing developments of the analysis tools needed to fulfill its physics program.
