CDMS II结果对MSSM中Higgs扇区的意义

Implications of CDMS II result on Higgs sector in the MSSM

Junji Hisano, Kazunori Nakayama, Masato Yamanaka

摘要:

我们研究了CDMS-II上两个暗物质候选事件对超对称标准模型中中性伴子暗物质的影响,并结合最近对核子奇异夸克含量的晶格模拟. Higgs交换过程决定了中性伴子与核子的散射速率,并对Bino-Higgsino混合态的中性伴子预言了重希格斯玻色子玻色子的质量.在Wino-Higgsino混合的情况下,Higgs扇区可能不受约束。

英文摘要:

We study implications of two dark matter candidate events at CDMS-II on the neutralino dark matter scenario in the supersymmetric standard model, in light of the recent lattice simulation on the strange quark content of a nucleon. The scattering rate of neutralino-nucleon is dominated by Higgs exchange processes and the mass of heavy Higgs boson is predicted for the neutralino of Bino-Higgsino mixing state. In the case of Wino-Higgsino mixing, the Higgs sector may not be constrained.
