Abstract
OPERA is a long baseline neutrino experiment which took data between 2008 and 2012 having for goal the observation of the νμâÎ½Ï transition in appearance mode i.e. detecting the Ï lepton. The detector was located in the underground Gran Sasso laboratory, 730 km away from the CNGS neutrino beam production at CERN. The collaboration observed 5 Î½Ï candidates which, considering the very low expected background of 0.25 events, allowed for a discovery claim of neutrino oscillation in appearance mode at the level of 5.1 Ï. Additional analyses were performed aiming at the possible observation of the νμâνe transition, and at the search for anomalies related to the possible existence of a sterile neutrino. In this paper, after a short introduction describing the detector, the different results are presented on both oscillation channels including standard 3 flavour scenario and possible new physics.
