Descripción
The OPERA experiment was designed to provide evidence of Nu_mu-->Nu_tau neutrino oscillations in appearance mode through the detection of the tau lepton produced in Nu_tau Charged Current interactions. The OPERA detector was exposed to the CNGS muon neutrino beam from CERN to Gran Sasso, 730 km away from the source, and collected data from 2008 to 2012.
We report on the search procedure for short-lived particles and on its validation on the charmed sample. Charmed hadrons, produced in about 4% of the neutrino interactions in OPERA, are an important background to the Nu_mu-->Nu_tau channel and an ideal control sample, as their decay exhibits topological and kinematical features strongly resembling those of the tau decay.
