Updated results on neutrino Non-Standard Interactions with KM3NeT/ORCA6
Original language description
KM3NeT/ORCA is an underwater neutrino telescope currently under construction in the Mediterranean Sea, with the goal of measuring atmospheric neutrino oscillation parameters and determining the neutrino mass ordering. KM3NeT/ORCA can additionally provide constraints on physics beyond the Standard Model which could appear through strong matter effects, such as the neutrino Non-Standard Interactions (NSIs). This work reports on the results of the NSIs search with the final dataset of ORCA6, the first configuration of ORCA with six detection units, which uses 433 kton-years of exposure and improved calibration, reconstruction and selection methods compared to previous works. The obtained bounds at 90% CL, |εμτ| <= 5.5 . 10-3, |εeτ| <= 7.8 . 10-2, |εeμ| <= 5.8 . 10-2 and -0.015 <= εττ - εμμ <= 0.016, are comparable to the current most stringent limits on any NSIs parameter.
