  • 摘要:We study pair annihilation processes of dark matter (DM) in the universe, in the case that the DM is an electroweak (EW) gauge non-singlet. In the current universe, in which the DM is highly non-relativistic, the non-perturbative e ect may enhance the DM annihilation cross sections, especially for that to two 's, by several orders of magnitude. We also discuss sensitivities in future searches for anomalous rays from the galactic center, which originate from DM annihilation.
