摘要:

我们在最小超对称标准模型的框架下研究了中性伴子暗物质的共湮灭区。在这个区域中,质量与中性伴子暗物质紧密简并的粒子存在,我们可以在轻子味被破坏的情况下解决锂问题。事实证明,索末菲增强是重要的共湮灭区,使暗物质信号变得足够大,可以观察到的电流灵敏度的间接实验。

英文摘要:

We have investigated neutralino dark matter in the framework of minimal supersymmetric Standard Model focusing on the coannihilatioin region. In this region, where the particle whose mass is tightly degenerated with the neutralino dark matter exists, we can solve the Lithium problem in the case of lepton flavor being violated. It turns out that Sommerfeld enhancement is important in the coannihilation region so that the dark matter signal becomes large enough to be observed by the current sensitivity of indirect experiments.
