Water Properties Studies with atmospheric muons in the ORCA/ARCA KM3NeT detector — •Evi Sakkou for the KM3NET-ERLANGEN collaboration — Erlangen Centre for Astroparticle Physics (ECAP), Friedrich-Alexander-Universität Erlangen-Nürnberg, Nikolaus-Fiebiger-Str. 2, 91058 Erlangen, Germany

The KM3NeT detector is an underwater neutrino observatory that detects atmospheric neutrinos in a range of energies. ORCA and ARCA detectors rely on precise knowledge of the optical properties of the surrounding water helping to enhance neutrino event reconstruction. In this study, we use atmospheric muons to study the water attenuation length. To this end we compare the light yield of muons between data and Monte Carlo simulations generated with different true values of the water attenuation length.
