Abstract:
'Neutrino Non Standard Interactions (NSI) are one of the sub-dominant effects which can affect neutrinos propagating through matter via observable changes in their oscillation patters predicted by the standard oscillation parameters. These interactions should modify neutrino flavour ratio observed in neutrino telescopes measuring atmospheric neutrino flux. The ANTARES neutrino telescope has already proven its sensitivity for NSI with 10 years of data taking. KM3NeT, the ANTARES successor, is a next-generation neutrino telescope currently under construction in the Mediterranea Sea. ORCA is a dense array that constitutes the low-energy branch of KM3NeT with the main aim of resolving the neutrino mass hierarchy. By now, the KM3NeT/ORCA Phase 1 has already been deployed, which makes 6 out of the planned 115 detection lines operational. Even with this limited capability, neutrino oscillations can already be measured and studied. In this contribution, the sensitivity to the neutrino Non-Standard Interactions (NSI) parameter $epsilon_{mu tau}$ using the current stage of the KM3NeT/ORCA detector together with the projections for the final configuration are presented.'
