Non-standard oscillations with KM3NeT

Several phenomena predicted by theories beyond the Standard Model manifest as modifications in the neutrino oscillation pattern. Large-volume Cherenkov detectors are able to observe atmospheric and cosmic neutrinos over a broad range of energies and baselines, making them powerful instruments for probing a variety of beyond Standard Model effects. KM3NeT is an infrastructure of two water Cherenkov detectors currently under construction in the Mediterranean Sea. The KM3NeT/ORCA detector is optimized for the precise measurement of atmospheric neutrino oscillation parameters at GeV energies, whereas KM3NeT/ARCA aims at the observation of high-energy astrophysical neutrinos. This contribution summarizes the results of several beyond Standard Model searches conducted with data from the partially deployed ORCA detector. Furthermore, future plans for exploring new physics effects at high energies with ARCA are discussed
