Results from the OPERA experiment
  The OPERA long baseline experiment located in the INFN Gran Sasso underground Laboratory was designed to establish the $\nu_{\mu}$ $\rightarrow$ $\nu_{\tau}$ oscillations in appearance mode, using the CNGS neutrino beam. Five $\nu_{\tau}$ candidate events have been detected in a data sample from the 2008-2012 runs, with a expected background of 0.25 events. The background only hypothesis is rejected with a significance larger than 5${\sigma}$. The analysis of the tau neutrino sample in the framework of the 3+1 neutrino model is presented. OPERA is able to identify $\nu_{e}$ CC events due to the good tracking capabilities of its target. The electron neutrino sample is also used to set limits on the 3+1 oscillation parameters.
