Asymmetric dark matter in braneworld cosmology
  We investigate the effect of a braneworld expansion era on the relic density
of asymmetric dark matter. We find that the enhanced expansion rate in the
early universe predicted by the Randall-Sundrum II (RSII) model leads to
earlier particle freeze-out and an enhanced relic density. This effect has been
observed previously by Okada and Seto (2004) for symmetric dark matter models
and here we extend their results to the case of asymmetric dark matter. We also
discuss the enhanced asymmetric annihilation rate in the braneworld scenario
and its implications for indirect detection experiments.
