Effects of CP-Violation in Neutralino Scattering and Annihilation
Paolo Gondolo, Katherine Freese
Abstract
We summarize our paper hep-ph/9908390, where we find that in some regions of supersymmetric parameter space, CP violating effects that mix the CP-even and CP-odd Higgs bosons can enhance the neutralino annihilation rate by factors of 106, and reduce the neutralino scattering rate off nucleons by factors of 10-7.
