考虑到极小性，我们重新检查了具有规范中介的模型。因此，我们得到了一个非常简单的直接规范中介模型，该模型不会受到风味问题或 CP 问题的影响。我们表明，通过 LHC 14TeV 运行的稳定状态搜索，可以测试与 126 GeV 左右的希格斯玻色子质量一致的参数空间。引力子是暗物质的可行候选者。我们还对我们的模型与 XMM 牛顿 X 射线天文台数据中最近发现的 3.5 keV X 射线线信号的可能联系进行了简短讨论。
We reexamine the models with gauge mediation in view of the minimality. As a result, we arrive at a very simple model of direct gauge mediation which does not suffer from the flavor problems nor the CP problems. We show that the parameter space which is consistent with the Higgs boson mass at around 126 GeV can be tested through the stable stau searches at the 14TeV run of the LHC. The gravitino is a viable candidate for a dark matter. We also give a short discussion on a possible connection of our model to the recently discovered X-ray line signal at 3.5 keV in the XMM Newton X-ray observatory data.
