The Di-Photon Excess in a Perturbative SUSY Model

We show that a 750 GeV di-photon excess as reported by the ATLAS and CMS experiments can be reproduced by the Minimal Dirac Gaugino Supersymmetric Standard Model (MDGSSM) without the need of any ad-hoc addition of new states. The scalar resonance is …

Interplay of gaugino (co)annihilation processes in the context of a precise relic density calculation

The latest Planck data allow one to determine the dark matter relic density with previously unparalleled precision. In order to achieve a comparable precision on the theory side, we have calculated the full $mathcalO(alpha_s)$ corrections to the most …

Neutralino-stop coannihilation into electroweak gauge and Higgs bosons at one loop

We compute the full O(alpha_s) supersymmetric QCD corrections for neutralino-stop co-annihilation into electroweak gauge and Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM). We show that these annihilation channels are …

Impact of SUSY-QCD corrections on neutralino-stop co-annihilation and the neutralino relic density

We have calculated the full O(alpha_s) supersymmetric QCD corrections to neutralino-stop co-annihilation into electroweak vector and Higgs bosons within the Minimal Supersymmetric Standard Model (MSSM). We performed a parameter study within the …
