An all-flavour search for diffuse astrophysical neutrino fluxes, using data obtained with the first KM3NeT/ARCA configurations, is presented. The KM3NeT research infrastructure includes two neutrino telescopes under construction with one of them, KM3NeT/ARCA, focusing on the detection of high energy neutrinos (>TeV) originated in 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| < 2o and |l| < 30o, in Galactic coordinates. The event selection is based on machine learning techniques and a bayesian method for the statistical analysis is employed.

Abstract
An all-flavour search for diffuse astrophysical neutrino fluxes, using data obtained with the first KM3NeT/ARCA configurations, is presented. The KM3NeT research infrastructure includes two neutrino telescopes under construction with one of them, KM3NeT/ARCA, focusing on the detection of high energy neutrinos (>TeV) originated in 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| < 2o and |l| < 30o, in Galactic coordinates. The event selection is based on machine learning techniques and a bayesian method for the statistical analysis is employed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
