从CDMS/XENON极限看SUSY暗物质

SUSY Dark Matter In Light Of CDMS/XENON Limits

Jin Min Yang

摘要:

在这次演讲中,我们简要回顾了目前CDMS/XENON对中性伴子暗物质的三种流行的超对称模型的约束:最小(MSSM),次最小(NMSSM)和近最小(nMSSM)。同时考虑了来自暗物质遗迹密度和各种对撞机实验的约束。结论是,对于每个模型,当前的CDMS/XENON限制可以很容易地排除由其他约束所允许的大部分参数空间,并且未来的SuperCDMS或XENON 100可以覆盖大部分允许的参数空间。在LHC的希格斯粒子搜索的影响进行了讨论。结果表明,在目前允许的参数空间中,MSSM荷电希格斯玻色子在LHC中很难被发现,而中性希格斯玻色子$H$和$A$在$μ$参数较大的参数空间中是可以被发现的.

英文摘要:

In this talk we briefly review the current CDMS/XENON constraints on the neutralino dark matter in three popular supersymmetric models: the minimal (MSSM), the next-to-minimal (NMSSM) and the nearly minimal (nMSSM). The constraints from the dark matter relic density and various collider experiments are also taken into account. The conclusion is that for each model the current CDMS/XENON limits can readily exclude a large part of the parameter space allowed by other constraints and the future SuperCDMS or XENON100 can cover most of the allowed parameter space. The implication for the Higgs search at the LHC is also discussed. It is found that in the currently allowed parameter space the MSSM charged Higgs boson is quite unlikely to be discovered at the LHC while the neutral Higgs bosons $H$ and $A$ may be accessible at the LHC in the parameter space with a large $μ$ parameter.
