Neutralino dark matter annihilation to monoenergetic gamma rays as a signal of low mass superstrings
We consider extensions of the standard model based on open strings ending on D-branes, in which gauge bosons and their associated gauginos exist as strings attached to stacks of D-branes, and chiral matter exists as strings stretching between intersecting D-branes. Under the assumptions that the fun...
