Results from the OPERA experiment in the CNGS beam

The OPERA experiment at the Gran Sasso underground laboratory was designed to study νμ → ντ oscillations in appearance mode in the CNGS neutrino beam. In this paper we report the detection of the 5th ντ candidate event found in the analysis of an enlarged data sample. Given the number of analysed ev...

Summary:The OPERA experiment at the Gran Sasso underground laboratory was designed to study νμ → ντ oscillations in appearance mode in the CNGS neutrino beam. In this paper we report the detection of the 5th ντ candidate event found in the analysis of an enlarged data sample. Given the number of analysed events and the low background, νμ → ντ oscillations have been established with a significance of 5.1σ. The analysis of the present electron neutrino sample in the framework of the 3 + 1 sterile model is also presented. Finally the analysis of the muon charge ratio in the cosmic ray sample is discussed.
