对暗物质湮灭的SUSY-QCD修正

SUSY-QCD corrections to dark matter annihilations

K. Kovarik, B. Herrmann

摘要:

我们提出了完整的QCD和超对称-QCD修正的中性伴子对湮灭成夸克-反夸克对。我们显示的结果和数值评估其影响的中性伴子湮灭截面和遗迹密度的情况下,非普遍的高吉诺群众。通过与由纯首阶计算得到的遗迹密度的比较,我们证明了修正对从宇宙学数据中提取超对称质量参数的影响。

英文摘要:

We present full QCD and SUSY-QCD corrections to neutralino pair annihilation into quark-antiquark pairs. We show results and numerically evaluate their impact on the neutralino annihilation cross section and the relic density in scenarios with non-universal gaugino masses. By comparing to the relic density obtained from a pure leading order calculation, we demonstrate that the corrections strongly influence the extraction of SUSY mass parameters from cosmological data.
