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…
