Summary: | International audience The KM3NeT/ORCA detector is a next-generation neutrino telescope at the bottom of the Mediterranean Sea. Optimized for the detection of atmospheric neutrinos with energies between 1 GeV and 100 GeV, KM3NeT/ORCA will offer competitive sensitivity for measuring the neutrino mass ordering, as well as $\theta_{23}$ and $\Delta m^2_{23}$. Currently under construction, 6 of the 115 planed Detection Units are already installed and are steadily taking data since January 2021. This contribution will present the results from the first neutrino oscillation analysis with 1 year of data. These early results already out-perform ANTARES measurements, and approach the sensitivity of current world-leading atmospheric neutrino experiments. The latest estimates of the sensitivity of the complete KM3NeT/ORCA detector are also discussed. |
