Description

The OPERA experiment was designed to observe the appearance of tau neutrino in the muon neutrino CNGS beam. This goal was successfully reached by observing a high purity sample of $\nu_\tau$ charged current (CC) interaction candidate events. Additionally, it was possible to isolate samples of $\nu_e$ and $\nu_\mu$ CC candidates, as well as neutral current candidate events. These four samples were used to put additional constraints on parameters of both standard neutrino mixing model and the $3+1$ sterile model. This talk will review the methodology of measuring neutrino interactions using the OPERA apparatus and give an overview of all results on neutrino oscillations produced by the experiment. In particular, a joint analysis of $\nu_\tau$ and $\nu_e$ samples will be shown which excludes a significant fraction of the sterile neutrino phase space allowed by MiniBooNE appearance analysis.
