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…
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…
The Role of Wino Content in Neutralino Dark Matter
Andreas Birkedal-Hansen, Brent D. Nelson
We investigate the dark matter prospects of supersymmetric models with nonuniversal gaugino masses. We find that for very particular values of the ratio of soft supersymmetry-break…
