Abstract
The OPERA experiment has been running with the CNGS neutrino beam from 2008 to 2012 and collected 1.8 × 1020 protons on target. Five tau neutrino candidates were observed, with a background of 0.25 events, leading to the discovery of tau neutrino appearance in a muon neutrino beam, reported in 2015. The analysis of the emulsion films is now completed. We report preliminary results obtained with the analysis of the final sample. We also report a study on cosmic-ray annual modulation. We then give some final remarks including the near future plans of the Collaboration.File | Dimensione | Formato | |
