Abstract

The OPERA experiment, exposed to the CERN to Gran Sasso nu(mu) beam, collected data from 2008 to 2012. Four oscillated nu(tau) Charged Current interaction candidates have been detected in appearance mode, which are consistent with nu(mu) -> nu(tau) oscillations at the atmospheric Delta m(2) within the "standard" three-neutrino framework. In this paper, the OPERA nu(tau) appearance results are used to derive limits on the mixing parameters of a massive sterile neutrino.
