Neutrino reconstruction with Graph Neural Networks in KM3NeT/ORCA6
KM3NeT is a series of neutrino telescopes under construction in the Mediterranean Sea. The detectors will consist of 3D arrays of 3’’ PMTs distributed on 115 vertical detection units (DUs), each containing 18 digital optical modules (DOMs), with each DOM hosting 31 PMTs. The ORCA detector is designe...
