太阳中性子湮灭产生的μ子:翻转的SU(5)

Muons from Neutralino Annihilations in the Sun: Flipped SU(5)

Muhammad Adeel Ajaib, Ilia Gogoladze, Qaisar Shafi

摘要:

我们考虑了两类超对称翻转SU(5)模型,它们具有引力介导的超对称破缺,使得热中性伴子残余丰度提供了宇宙中观测到的暗物质密度。我们估计的μ介子通量所引起的中微子产生的中性粒子湮灭在太阳和讨论的前景,在冰立方/深核实验检测这种通量。我们还提供了相应的通量在约束最小超对称标准模型和非通用希格斯模型的比较。确定了IceCube/DeepCore实验可以探索的参数空间中的区域。

英文摘要:

We consider two classes of supersymmetric flipped SU(5) models with gravity mediated supersymmetry breaking such that the thermal neutralino relic abundance provides the observed dark matter density in the universe. We estimate the muon flux induced by neutrinos that arise from neutralino annihilations in the Sun and discuss prospects for detecting this flux in the IceCube/Deep Core experiment. We also provide comparisons with the corresponding fluxes in the constrained minimal supersymmetric standard model and non-universal Higgs models. Regions in the parameter space that can be explored by the IceCube/DeepCore experiment are identified.
