Abstract
The expectation for detecting with the KM3NeT/ARCA telescope, signals from Starburst Galaxies, both as diffuse signal and as point-like excess, is presented. A recent theoretical model was used for the diffused flux. The model, which has been developed by authors of this contribution, takes into account a “blending” of spectral indices to describe the spectral energy distribution. For the point-like search approach, the most promising local starburst galaxies to be observed as point-like neutrino excesses were considered: NGC 1068, the Small Magellanic Cloud and the Circinus Galaxy. For the diffuse analysis, the sensitivity for two ARCA building blocks is provided, considering both track and shower events, in the range of 100GeV − 100PeV. For the point-like analysis, the sensitivity for two ARCA building blocks is provided considering only track events. ARCA has the potential to constrain the selected phenomenological scenarios, showing the minimum of the sensitivity where the theoretical spectral energy distributions are expected to peak. This could provide evidence of the link between star-forming processes and hadronic emissions.
