Study of Neutrino Oscillations in the OPERA Experiment

The OPERA experiment has been designed to perform the first detection of neutrino oscillations in direct appearance mode in the $ν_μ\toν_τ$ channel, through the detection of the tau lepton produced in charged current interaction on an event by event basis. The detector is hybrid, being made of an emulsion/lead target and of electronic detectors. It exploited the CNGS muon neutrino beam from CERN to Gran Sasso, 730 km from the source. Runs with CNGS neutrinos were successfully carried out from 2008 to 2012. We report on the large data sample analysed so far and give our results on the search for $ν_μ\toν_τ$ and $ν_μ\toν_{e}$ oscillations.
