带有轻希格斯粒子的中微子暗物质

Neutralino dark matter with a Light Higgs

Andreas Goudelis

摘要:

我们研究了在规范耦合统一尺度下具有非普适希格斯质量的超对称场景中的中性伴子暗物质现象,该规范耦合统一尺度可以容纳轻希格斯玻色子,其中正确的残余密度主要通过湮灭成赝标量A来获得。我们的分析表明,A极区的大部分可以产生可探测的γ射线和反质子信号。我们进一步关注影响间接和主要是直接检测结果的不确定性。

英文摘要:

We examine the neutralino dark matter phenomenology in supersymmetric scenarios with nonuniversal Higgs masses at the gauge coupling unification scale that can acommodate a light Higgs boson, where the correct relic density is obtained mostly through the annihilation into a pseudoscalar A. Our analysis shows that most part of the A pole region can produce detectable gamma-ray and antiproton signals. We further focus on uncertainties influencing the results in indirect and mainly direct detection.
