摘要:

最近,ATLAS和CMS合作报告了一个令人兴奋的线索,即一个质量约为125 GeV的类似标准模型的希格斯玻色子。这样的希格斯玻色子质量可以很容易地在基于“纯引力中介模型”的最小超对称标准模型中获得,其中sfermion质量和希格斯质量参数在几十到几百TeV的范围内,而gauginos在几百GeV到TeV的范围内。本文讨论了纯引力中介模型中的高更质量谱的细节。我们还讨论了该模型在当前和未来的实验中的信号,如宇宙线观测和LHC实验。特别是,我们表明,参数空间,这是一致的热leptogenesis可以充分调查实验在可预见的未来。

英文摘要:

Recently, the ATLAS and CMS collaborations reported exciting hints of a Standard Model-like Higgs boson with a mass around 125GeV. Such a Higgs boson mass can be easily obtained in the minimal supersymmetric Standard Model based on the "pure gravity mediation model" where the sfermion masses and the Higgs mass parameters are in tens to hundreds TeV range while the gauginos are in the hundreds GeV to TeV range. In this paper, we discuss detalis of the gaugino mass spectrum in the pure gravity mediation model. We also discuss the signals of the model at the current and future experiments such as cosmic ray observations and the LHC experiments. In particular, we show that the parameter space which is consistent with the thermal leptogenesis can be fully surveyed experimentally in the foreseeable future.
