Phenomenological Aspects of Heterotic Orbifold Models at One Loop

Pierre Binetruy, Andreas Birkedal-Hansen, Yann Mambrini +1

We provide a detailed study of the phenomenology of orbifold compactifications of the heterotic string within the context of supergravity effective theories. Our investigation focu…

rSUGRA: Putting Nonuniversal Gaugino Masses on the (W)MAP

Andreas Birkedal-Hansen

In this talk, we investigate the relic density and direct detection prospects of rSUGRA, a simple paradigm for supersymmetry breaking that allows for nonuniversal gaugino masses. W…

Scalar Dark Matter From Theory Space

Andreas Birkedal-Hansen, Jay G. Wacker

The scalar dark matter candidate in a prototypical theory space little Higgs model is investigated. We review all details of the model pertinent to dark matter. We perform a therma…

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…
