Neutrino oscillation analysis with 715 kton-years of KM3NeT/ORCA

KM3NeT/ORCA is a water-Cherenkov neutrino telescope currently under construction in the depths of the Mediterranean Sea. Its primary goal is to study atmospheric oscillations and to determine the neutrino mass ordering. The detector consists of a three-dimensional array of strings, each equipped with 18 digital optical modules containing 31 photomultiplier tubes. At present, 28 out of the planned 115 strings have been deployed and are actively collecting data. The modular design of KM3NeT/ORCA allows for physics analyses even before full detector completion. In this contribution, we present measurements of neutrino oscillation parameters using partial detector configurations with six, ten, and eleven strings, as well as comparisons with the existing worldwide measurements.
