Summary: | The ICARUS-T600 detector is the first large-scale liquid Argon TPC ever operated; its successful data-taking campaign at Gran Sasso laboratory, with CNGS beam and atmospheric neutrinos, proved the maturity of this innovative detection technology. In particular, it performed a search for sterile neutrinos through νμ to νe oscillations, observing no excess w.r.t. backgrounds and allowing to strongly constrain the parameter space, indicating a narrow region in agreement with all experimental data.
A definitive answer to the sterile neutrino puzzle will be given by the SBN experiment at the Booster beam at FNAL, where ICARUS-T600 will act as far detector, by performing both appearance and disappearance measurements.
