Status of tau appearance sensitivities and measurements with KM3NeT/ORCA — •Nicole Geißelbrecht for the ANTARES-KM3NET-ERLANGEN collaboration — Friedrich-Alexander-Universität Erlangen-Nürnberg, ECAP

KM3NeT/ORCA is a water Cherenkov detector currently under construction in the Mediterranean Sea. The primary goals are the study of neutrino oscillations and the determination of the neutrino mass ordering. One of the main physics objectives in the early phase of ORCA is a measurement of the appearance of tau neutrinos.
Tau neutrinos detected by ORCA are a pure product of neutrino oscillations since ORCA is optimized for atmospheric neutrinos that are almost exclusively produced as electron and muon neutrinos. Even though they can only be measured indirectly as an excess of shower-like events compared to the non-oscillation scenario, their detection will offer valuable information.
One of the first requirements for this study is a reliable particle identification (PID). Therefore, existing PID algorithms need to be optimized with regard to charged current tau neutrino interactions. This talk will report about the first efforts and results using classical machine learning techniques based on boosted decision trees
