The OPERA experiment has been designed to perform the first detection
of neutrino oscillations in the Numu to Nutau channel, in direct
appearance mode through the event by event detection of the tau lepton
produced in Nutau Charged Current interactions.
OPERA is a hybrid detector, made of emulsion/lead target elements and
of electronic detectors, placed in the CNGS muon neutrino beam from
CERN to Gran Sasso, 730 km away from the source. Neutrino interactions
from the CNGS neutrino runs have been recorded from 2008 until the end
of 2012. We shall report on the data sample analysed so far and give the
latest OPERA results on Numu to Nutau and Numu to Nue oscillation
searches.
