Abstract

The OPERA experiment reached its main goal by proving the appearance of v_τ in the CNGS v_μ beam. Five v_τ candidates were detected with a S/B ratio of ∼ 10, allowing to reject the null hypothesis at 5.1σ. The search has been extended by loosening the selection criteria in order to improve the statistical uncertainty. One of the v_τ candidates selected with the new strategy shows a double vertex topology and, after a dedicated multivariate analysis, is compatible with being a v_Tτ interaction with charm production. Based on the enlarged data sample the estimation of Δm²₂3 in appearance mode is being performed. The search for v_e interactions has been extended over the full data set with a more than twofold increase in statistics: data are compatible with the non-oscillation hypothesis in the three-flavour mixing model. The implications of the electron neutrino sample in the framework of the 3+1 sterile mode will lead to exclusion limits on sin² 2θ_μe. Finally, the analysis of the annual modulation of cosmic muons is introduced.
