Description

In this talk, I will show how to calculate the bound state formation cross section in this model. Unlike the usual calculations, "mono-pole" emission becomes significant, and the process emitting the longitudinal dark photon/Goldstone boson becomes very important in the annihilation processes. I will also show the numerical results.
