论文摘要
在kachru-kallosh-linde-trivedi（KKLT）通量紧凑型中实现的幻影介导可以自然地抑制低能尺度上的上型Higgs软质量。结果，与常规场景相比，如果希格西诺斯（Higgsinos）比重型希格斯（Higgs Doublet）轻得多，则可以将电动调整的程度进一步降低到循环因子。有趣的是，只要量规耦合统一（作为海市rage仪调解的先决条件）可容纳这种轻度的希格西诺斯，即使在高尺度的超对称性中也可以保持高度超对称性。在观察到的希格斯玻色子上的实验限制下，事实证明，如果Higgsinos在几百个GEV附近或低于下方的情况下，则幻影调解可以表现出低于2至6 TeV的停靠点，即在大约2到6 TEV之间表现出低比百分之几的微调。
Mirage mediation realized in the Kachru-Kallosh-Linde-Trivedi (KKLT) flux compactification can naturally suppress the up-type Higgs soft mass at low energy scales. As a result, compared to the conventional scenarios, the degree of electroweak fine-tuning can be reduced further up to by a loop factor if the Higgsinos are much lighter than the heavy Higgs doublet. Interestingly, this feature holds even in high-scale supersymmetry as long as the gauge coupling unification, which is required as a prerequisite for mirage mediation, accommodates such light Higgsinos. Under the experimental constraints on the observed Higgs boson, it turns out that mirage mediation can exhibit low electroweak fine-tuning better than a few percent for stops between about 2 and 6 TeV, i.e., at the same level as in the weak scale supersymmetry, if the Higgsinos are around or below a few hundred GeV.
