Sommerfeld enhancements with vector, scalar and pseudoscalar force-carriers
Ze-Peng Liu, Yue-Liang Wu, Yu-Feng Zhou
The first AMS-02 measurement confirms the existence of an excess in the cosmic-ray positron fraction previously reported by the PAMELA and Fermi-LAT experiments. If interpreted in…

Dark matter conversion as a source of boost factor for explaining the cosmic ray positron and electron excesses
Ze-Peng Liu, Yue-Liang Wu, Yu-Feng Zhou
In interacting multi-component dark matter (DM) models, if the DM components are nearly degenerate in mass and the interactions between them are strong enough, the relatively heavy…

Enhancement of dark matter relic density from the late time dark matter conversions
Ze-Peng Liu, Yue-Liang Wu, Yu-Feng Zhou
We demonstrate that if the dark matter (DM) in the Universe contains multiple components,the interactions between the DM components may induce DM conversions. It is then possible t…
