Dark Atoms and the Positron-Annihilation-Line Excess in the Galactic Bulge
It was recently proposed that stable particles of charge −2, O--, can exist and constitute dark matter after they bind with primordial helium in O-helium (OHe) atoms. We study here in detail the possibility that this model provides an explanation for the excess of gamma radiation in th...
