Description
KM3NeT/ORCA will be a Cherenkov neutrino detector of approximately 7 Mton under construction at a depth of 2450 meters in the Mediterranean Sea, off the coast of Toulon, France. The detector is designed as an array of 115 detection lines composed of multi-photomultipliers optical modules. Its primary scientific goals are the determination of the neutrino mass ordering as well as the measurement of neutrino oscillation parameters with high precision using atmospheric neutrinos.
ORCA has been in operation since 2017, and this analysis is based on 4 years of data collected from February 2020 to January 2024 using detector configurations ranges from 6 to 18 detection lines. This contribution focuses on the latest KM3NeT/ORCA measurements of the neutrino oscillation parameters $\Delta m^2_{31}$ and $\theta_{23}$, together with our latest measurement of the neutrino mass ordering.
