Cosmological implications of supersymmetric CP violating phases

TL;DR

This paper investigates how supersymmetric CP-violating phases influence dark matter detection, finding they have minimal impact on relic density but significantly enhance detection rates.

Contribution

It demonstrates that large SUSY phases do not affect relic density but substantially increase detection rates, highlighting their importance in dark matter experiments.

Findings

Large SUSY phases do not alter LSP relic density.

CP phases significantly boost direct detection rates.

CP phases enhance indirect detection signals.

Abstract

We show that large SUSY phases have no significant effect on the relic density of the lightest supersymmetric particle (LSP). However, they are very significant for the detection rates. We emphasise that the phase of the trilinear coupling increase the direct and indirect detection rates.
