Description
KM3NeT/ORCA is a water-Cherenkov neutrino telescope under construction in the Mediterranean sea, the main goals of ORCA consist in measuring atmospheric neutrino oscillations and determining the neutrino mass ordering.
The detector is located 40 km off-shore Toulon, France, and consists of a three-dimensional grid of photo-multiplier tubes. The final detector will consist of 115 detection units equipped with 18 digital optical modules, housing 31 photo-multiplier tubes each.
By reconstructing the arrival direction of GeV-neutrinos crossing the Earth and interacting within the detector vicinity, ORCA can effectively constrain the oscillation parameters of atmospheric neutrinos. This presentation covers the most up-to-date results from the ORCA detector with an exposure of 715 kt-y on neutrino standard oscillations, which improve on previous ORCA measurements and benefit from increased exposure, refined event selections and optimized reconstruction algorithms.
