Experimental picture of an observed event with a clearly identified electron signature out of the total sample of 1091 neutrino interactions. This event has a total energy of 11.5 ± 1.8 GeV, and a transverse electron momentum of 1.8 ± 0.4 GeV/c, while the single electron shower in the transverse plane is clearly opposite to the remaining of the event.

Weighing 760 tonnes, ICARUS T600 is the world’s largest liquid argon neutrino detector. It was operated by an international collaboration in the Gran Sasso laboratory in Italy from 2009 to 2012.

ICARUS detector’s time projection chambers (TPC) will now be overhauled at CERN in preparation for possible new uses in future experiments. 

A Multi-detector program will address the unexplained anomalies which together could be hinting at new physics (steriles?) .

  • Most common interpretation is as evidence for high mass-squared neutrino oscillations and the existence of one or more additional, mostly “sterile” neutrino states with masses at or below a few eV.
  • While each of these measurements taken separately lack the significance to claim a discovery, together these signals could be hinting at important new physics that requires further exploration

Experimental anomalies ranging in significance (2.8–3.8σ) have been reported from a variety of experiments studying neutrinos over baselines less than 1 km. Current anomalies from: accelerator beams radioactive sources reactor neutrinos
