中性伴子湮灭的SUSY-QCD修正对Higgs漏斗中冷暗物质遗迹密度的影响

Effect of SUSY-QCD corrections to neutralino annihilation on the cold dark matter relic density in the Higgs funnel

Björn Herrmann

摘要:

本文给出了mSUGRA模型中A-漏斗区的主要过程--赝标希格斯玻色子交换导致中性伴子对湮灭为底夸克-反夸克对的QCD和SUSY-QCD修正的完整计算.我们提出的湮灭截面的数值预测和讨论的影响,冷暗物质遗迹密度与最近的宇宙学数据的校正项。

英文摘要:

We present a complete calculation of the QCD and SUSY-QCD corrections to neutralino pair annihilation into bottom quark-antiquark pairs through exchange of a pseudoscalar Higgs boson, which is the dominant process in the cosmological A-funnel region of the mSUGRA model. We present numerical predictions for the annihilation cross section and discuss the influence of the correction terms on the cold dark matter relic density with respect to recent cosmological data.
