NUGM + NUHM2模型中的μ介子g-2和暗物质

Muon g-2 and Dark Matter in the NUGM + NUHM2 model

M. Adeel Ajaib, Fariha Nasir

摘要:

我们分析了NUGM + NUHM 2模型,并研究了最近的实验约束对该模型的参数空间的影响。我们还探讨了该模型中的暗物质的性质,并提出了由中性伴子的各种成分所表征的参数空间。更严格地探索的参数空间的区域,满足观测到的μ子的异常磁矩的偏差。我们还提出了相应的结果的产生截面和衰变宽度的光CP-偶希格斯玻色子和观察到,有一个狭窄的区域的参数空间对应的光stau解释了所观察到的偏离μ子g-2,也导致增强的希格斯生产和衰变宽度。

英文摘要:

We analyze the NUGM + NUHM2 model and study the implications of recent experimental constraints on the parameter space of this model. We also explore the nature of dark matter in this model and present the parameter space characterized by various compositions of the neutralino. The region of the parameter space that satisfies the observed deviation in the anomalous magnetic moment of the muon is explored more rigorously. We also present results corresponding to the production cross section and decay widths of a light CP-even Higgs boson and observe that there is a narrow region of the parameter space corresponding to a light stau which explains the observed deviation in the muon g-2 and also leads to enhancement in the Higgs production and decay widths.
