ORCA sensitivity to ντ appearance — •Lukas Maderer for the KM3NeT-ECAP collaboration — ECAP / Universität Erlangen-Nürnberg

The deep-sea neutrino detector KM3NeT/ORCA is optimized to study oscillations of atmospheric neutrinos in the few-GeV energy range. Apart from the primary science goal of ORCA - to resolve the neutrino mass hierarchy - the detector will be sensitive to the ντ flux developing from oscillations from a purely νµ and νe atmospheric flux along its passage through the Earth. Precise measurements of the ντ flux normalization facilitate the investigation of deviations from the expected unitarity of the PMNS matrix.

The upcoming installation of its first detector strings (about 5% of full detector with 115 strings) will already provide considerable atmospheric neutrino statistics with about 450 detected ντ events per year. This talk will present performance studies of a 7-string ORCA array and its sensitivity to exclude ντ non-appearance within the first months of operation.
