The OPERA experiment at the Gran Sasso underground laboratory was designed to study vμ → vτ oscillations in appearance mode in the CNGS neutrino beam. Five vτ candidate events have been observed, allowing to assess the discovery of vμ → vτ transitions in the atmospheric sector with a significance of 5.1σ. In this paper the vτ data analysis will be discussed, with emphasis on the background constraints obtained using dedicated data-driven control samples. Results on the search for vμ → vτ oscillations, on the search for sterile neutrino mixing and on the atmospheric muon charge ratio will also be presented.
