Abstract

KM3NeT/ARCA is a rapidly evolving neutrino detector in the Mediterranean Sea. The capability of the detector to measure the diffuse astrophysical neutrino flux was recently demonstrated by the observation of an ultra-high-energy neutrino of astrophysical origin. In this contribution, an analysis of KM3NeT/ARCA data, employing machine learning techniques and advanced statistical methods is presented, as well as a fit to the parameters of the diffuse flux. The latest results for the diffuse cosmic neutrino flux with KM3NeT/ARCA will be reported.
