B. Herrmann, M. Klasen (LPSC Grenoble)
TL;DR
This paper calculates detailed SUSY-QCD corrections to dark matter annihilation in the Higgs funnel, showing their significant impact on SUSY parameter extraction from cosmological data.
Contribution
It provides the full O(alpha_s) SUSY-QCD corrections including resummation of large contributions, enhancing the accuracy of dark matter annihilation predictions.
Findings
Corrections significantly affect SUSY parameter extraction.
Resummation of large contributions is essential.
Corrections must be included in analysis tools like DarkSUSY or micrOMEGAs.
Abstract
We compute the full O(alpha_s) SUSY-QCD corrections to dark matter annihilation in the Higgs-funnel, resumming potentially large mu tan beta and A_b contributions and keeping all finite O(m_b,s,1/tan^2 beta) terms. We demonstrate numerically that these corrections strongly influence the extraction of SUSY mass parameters from cosmological data and must therefore be included in common analysis tools such as DarkSUSY or micrOMEGAs.
