Abstract

The energy-dependent expectations for the full KM3NeT/ARCA detector, both for diffuse and point-like signals are presented. For the diffuse analysis, the 90% C.L. quasi-differential sensitivity for 10 years of the full detector operations is computed, and compared with the IceCube measured diffuse spectrum. The whole energy range observable by ARCA ∼ (1 TeV − 100 PeV) is taken into account, selecting upgoing track-like as well as all-sky cascade-like events. For the point-like analysis, the differential sensitivity for several declinations is computed, selecting upgoing tracks νμ and ν̄μ charge-current interactions. Some particular starburst galaxies (SBGs) are considered such as NGC 1068, the Small Magellanic Cloud (SMC) and Circinus Galaxy. The resulting sensitvities demonstrate the importance of KM3NeT/ARCA to link star-forming processes with high-energy neutrino production within a few years of operation.
