Description
Galactic Center Excess (GCE) remains one of the most interesting unknown signals in the domain of few GeV gamma-rays. Since its morphology prefers spherical symmetry, dark matter annihilation can be an intriguing explanation of the GCE. In this work, we tested the possibility of cascade annihilation of dark matter, such as into four-b quarks with boost effect. At the same time, utilizing the observation data towards dwarf galaxies and observation of anti-proton flux of AMS-02 experiment, we set strong bound on the explanation of GCE in terms of dark matter annihilation.
