Constraining sub-GeV dark matter with the Integral data

Abstract: The goal of this work is to constrain sub-GeV dark matter particles (1 MeV <= mDM <= 5 GeV) by looking at photons in the keV energy range and by including the inverse Compton scattering contribution to the total flux. In particular, the electrons and positrons produced by dark matter particles can scatter the low-energy photons in the Milky Way up to the X-ray energies. These X rays are probed by the Integral data, which we utilised to constrain the dark matter annihilation cross-section. The relevant annihilation channels are electron, muon and pion. As a result, we derived competitive bounds for dark matter particles with a mass between 150 MeV and 1.5 GeV.
