511 KeV Photons From Color Superconducting Dark Matter

Abstract

We discuss the possibility that the recent detection of 511 keV gamma rays from the galactic bulge, as observed by INTEGRAL, can be naturally explained by the supermassive very dense droplets (strangelets) of dark matter. These droplets are assumed to be made of ordinary light quarks (or antiquarks) condensed in non-hadronic color superconducting phase. The droplets can carry electrons (or positrons) in the bulk or/and on the surface. The e^+e^- annihilation events take place due to the collisions of electrons from the visible matter with positrons from dark matter droplets which may result in the bright 511 KeV gamma-ray line from the bulge of the Galaxy.
