Size Dependence of the Sommerfeld Enhancement for Puffy Dark Matter
Wu-Long Xu, Jin Min Yang, Wen-Na Yang
We examine the size effects in the Sommerfeld enhancement factor for puffy dark matter annihilation. First, we use the partial-wave method to study the case of puffy dark matter fo…

Scattering of non-relativistic finite-size particles and puffy dark matter direct detection
Wu-Long Xu, Jin Min Yang, Jun Zhao
In this work we consider the scattering between non-relativistic particles with different finite sizes. We first calculate their interaction potential and apply the partial wave me…

Direct detection of Higgs portal for light self-interacting dark matter
Wu-Long Xu, Jin Min Yang, Bin Zhu
Self-interacting dark matter (SIDM) can address the small-scale anomalies and previous researches focused on such a SIDM heavier than GeV, for which the self-scattering cross-secti…
