A new way of detecting tau neutrinos

In this letter, a new kind of neutrino data analysis is proposed, which considers the special kinematic properties of charged current tau neutrino interactions which stimulate neutral currents due to hadronic decay of the tau lepton. It is shown that the differential cross section, with respect to a suitable scaling variable, of “true” neutral currents differs significantly from tau induced events. This analysis is shown to have good sensitivity for the presence of ν_gt interactions.
