摘要: We show that the GeV scale -ray excess from direction of Galactic Center can be naturally explained by pair annihilation Abelian vector dark matter (VDM) into a Higgs bosons V → ��, followed subsequent decay � bb,�¯ �. All processes are described renormalizable VDM model with portal, which is flavor-dependent. Some parameter space this scenario tested at near future direct search experiments such as LUX and XENON1T.
