Relic Neutralino Densities and Detection Rates with Nonuniversal Gaugino Masses
Andreas Birkedal-Hansen, Brent D. Nelson
We extend previous analyses on the interplay between nonuniversalities in the gaugino mass sector and the thermal relic densities of LSP neutralinos, in particular to the case of m…

Gaugino and Higgsino Coannihilations I: Neutralino-Neutralino Interactions
A. Birkedal-Hansen, E. Jeong
We present exact analytic cross sections for all neutralino-neutralino coannihilations into two-body tree level final states. These expressions allow the calculation of important c…

SUSY dark matter with non-universal gaugino masses
Andreas Birkedal-Hansen
In this talk we investigate the dark matter prospects for supersymmetric models with non-universal gaugino masses. We motivate the use of non-universal gaugino masses from several…
