| Summary: | The 760-ton ICARUS T600 detector has completed a successful three-year physics run at the underground LNGS laboratories, searching for atmospheric neutrino interactions and, with the CNGS neutrino beam from CERN, performing a sensitive search for LSND-like anomalous <inline-formula> <math display="inline"> <semantics> <msub> <mi>ν</mi> <mi>e</mi> </msub> </semantics> </math> </inline-formula> appearance, which contributed to constraining the allowed parameters to a narrow region around <inline-formula> <math display="inline"> <semantics> <mo>Δ</mo> </semantics> </math> </inline-formula>m<inline-formula> <math display="inline"> <semantics> <mrow> <msup> <mrow></mrow> <mn>2</mn> </msup> <mo>∼</mo> </mrow></semantics></math></inline-formula>eV<inline-formula> <math display="inline"> <semantics> <msup> <mrow></mrow> <mn>2</mn> </msup> </semantics> </math> </inline-formula>, where all the experimental results can be coherently accommodated at 90% C.L. The T600 detector underwent a significant overhaul at CERN and has now been moved to Fermilab, to be soon exposed to the Booster Neutrino Beam (BNB) to search for sterile neutrinos within the SBN program, devoted to definitively clarifying the open questions of the presently-observed neutrino anomalies. This paper will address ICARUS’s achievements, its status, and plans for the new run and the ongoing analyses, which will be finalized for the next physics run at Fermilab.
