Summary: | International audience KM3NeT is a next-generation research infrastructure being installed in the Mediterranean Sea. Within this infrastructure, KM3NeT/ORCA is a future neutrino detector optimised for the mea- surement of the neutrino mass hierarchy (NMH) by investigating atmospheric neutrino oscillation in matter in the energy range above 5 GeV. Charged-current muon-neutrino events significantly contribute to the NHM sensitivity [ 1 ]. In these events, the generated muon induces a track-like topology. The precise reconstruction of such events is an indispensable prerequisite for the NMH measurement. The algorithm described here reconstructs the neutrino direction, the neutrino en- ergy, the position of the interaction vertex and estimates the inelasticity of the neutrino interaction. The performances achieved, in terms of resolutions and efficiency, are presented |
