Neutralino-Neutralino pair annihilation crosssections with flavour violation

TL;DR

This paper provides the first exact calculations of neutralino-neutralino annihilation cross sections considering flavor violation, which are crucial for dark matter relic density and detection studies.

Contribution

It introduces the most general and exact neutralino-neutralino annihilation cross sections incorporating flavor violation, filling a gap in existing literature.

Findings

First exact calculations including flavor violation

Abstract

We present the first exact and most general neutralino-neutralino annihilation cross sections in the presence of flavor violation. The existing set of calculations in literature do not include flavour violation. These calculations are important for the calculation of relic density and indirect detection of dark matter in various experiments.
