We present the expectations of ARCA detector for starburst galaxies (SBGs) observation, as a diffuse signal. To describe the diffuse flux, we make use of a recent theoretical model which implemented a “blending” of spectral indexes for high-energy spectral energy distributions. For the analysis, we provide the 5−year differential sensitivity for two ARCA building blocks, considering both track and shower events, in the range of 100 GeV - 10 PeV. We found that 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. A significant neutrino detection would provide a compelling evidence of the link between star-forming processes and hadronic emissions.
