Investigations of hadronic vs electromagnetic cascade identification at the PeV energy scale. — •Yara Darras for the ANTARES-KM3NET-ERLANGEN collaboration — Nikolaus-Fiebiger-Str. 2 91058 Erlangen, Germany

KM3NeT/ARCA is an underwater Cherenkov detector located 100 km off-shore Portopalo di Capo Passero on the south-eastern coast of Sicily. Its main goal is the detection of high energy neutrinos from astrophysical sources such as gamma ray bursts or active galactic nuclei. Neutrino interactions with matter are detected as events of different topologies depending on the neutrino flavour and interaction type. The Glashow resonance is a particular type of neutrino interaction in which an electron antineutrino with an energy of about 6.3 PeV interacts with an electron producing a W-boson which can decay through different channels. In this contribution, the use of deep learning techniques to distinguish between hadronic and leptonic decay modes of the W boson produced in the Glashow resonance is described.
