Limits on muon-neutrino to tau-neutrino oscillations induced by a sterile neutrino state obtained by OPERA at the CNGS beam

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 ${\nu }_{\mu }\to {\nu }_{\tau }$ 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.
