Galactic center GeV gamma-ray excess, from dark matter with gauged lepton numbers
The recently observed excess in gamma-ray signal near the Galactic center suggests that dark matter particles may annihilate into charged fermions that produce gamma-ray to be observed. In this paper, we consider a leptonic dark matter, which annihilates into the standard model leptons, μ+μ− and τ+τ...
