Description

In this contribution the most recent results of an all-flavour search for diffuse astrophysical neutrino fluxes, using the full dataset obtained with the first KM3NeT/ARCA configurations, will be presented. KM3NeT/ARCA is part of the KM3NeT research infrastructure and focuses on the detection of high energy neutrinos (>TeV) from astrophysical sources. The KM3NeT/ARCA detection units are deployed offshore Capo Passero, Italy at a depth of 3500 m, delivering data as the construction of the detector is ongoing. The two search cases considered here are an all-sky diffuse flux and a flux coming from the Galactic Ridge, namely |b| < 2 ◦and |l| < 30 ◦ , in Galactic coordinates. The event selection is based on machine learning techniques and a bayesian method for the statistical analysis is employed.
