Relic Density of Asymmetric Dark Matter with Breit-Wigner Enhancement
Fangyu Liu, Hoernisa Iminniyaz, Qiquan Li
Abstract
The Breit-Wigner Enhancement mechanism provides a novel interpretation for the ``enhancement factor'' derived from data of the PAMELA, ATIC, and PPB-BETS experiments, and we further extends this research to the case of asymmetric Dark Matter. We investigate the impact of resonance mechanism to the asymmetric Dark Matter case and constrain the resonance model parameters to satisfy the ``enhancement factor" and the asymmetric dark matter model parameters to meet the upper bound requirement imposed by the astronomical experiment.
