Procedure for short-lived particle detection in the OPERA experiment and its application to charm decays

Abstract

The OPERA experiment, designed to perform the first observation of ${\nu }_{\mu }\to {\nu }_{\tau }$ oscillations in appearance mode through the detection of the $\tau$ leptons produced in ${\nu }_{\tau }$ charged current interactions, has collected data from 2008 to 2012. In the present paper, the procedure developed to detect $\tau$ particle decays, occurring over distances of the order of 1 mm from the neutrino interaction point, is described in detail. The results of its application to the search for charmed hadrons are then presented as a validation of the methods for ${\nu }_{\tau }$ appearance detection.
