Recent results of the OPERA experiment

Abstract

The OPERA experiment aims at the direct confirmation of the leading oscillation mechanism in the atmospheric sector looking for the appearance of $\nu_{\tau}$ in an almost pure $\nu_{\mu}$ beam (the CERN CNGS beam). In five years of physics run the experiment collected $17.97 \times 10^{19}$ p.o.t. The detection of $\tau$s produced in $\nu_{\tau}$ CC interactions and of their decays is accomplished exploiting the high spatial resolution of nuclear emulsions. Furthermore OPERA has good capabilities in detecting electron neutrino interactions, setting limits on the $\nu_{\mu} \rightarrow \nu_{e}$ oscillation channel. In this talk the status of the analysis will be presented together with updated results on both oscillation channels.
