Corrections to Bino Annihilation II: One-Loop Contribution to $\widetilde B \widetilde B \to Z^*$

arXiv:hep-ph/9402233 · doi:10.1016/0370-2693(94)91203-3

Abstract

We calculate the one-loop contribution to the bino annihilation rate due to the process $\widetilde B \widetilde B \to Z^*$, which vanishes at tree level.
