International audience ORCA (Oscillations Research with Cosmics in the Abyss) is the low-energy detector of KM3NeT, the next generation underwater Cherenkov neutrino detector in the Mediterranean Sea. Although its primary goal is to determine the Neutrino Mass Ordering (NMO) with atmospheric neutrinos, its access to a wide range of energies and baselines makes it optimal to discover exotic physics beyond the Standard Model (SM) such as Non-Standard Interactions (NSI).Non-Standard Interactions with neutrinos will introduce modifications in the SM potential, which will alter the event spectra at the ORCA detector. Using these NSI induced distortions inthe flavour content over three flavour standard oscillations, it is possible to constrain NSI modelparameters. This report outlines the sensitivity that ORCA can achieve in puttingupper bounds on some of these non-standard neutrino interaction parameters.
