چکیده انگلیسی
OPERA is a long baseline neutrino experiment which took data between 2008 and 2012 having for goal the observation of the νμ→ντ transition in appearance mode i.e. detecting the τ 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 ντ 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 σ. Additional analyses were performed aiming at the possible observation of the νμ→νe 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.
