我们研究了次小超对称标准模型。我们考虑软超对称破缺参数，这些参数是由超对称破缺的海市蜃楼中介机制引起的。我们专注于海市蜃楼中介，其中所谓的海市蜃楼尺度就是TeV尺度。在这种情况下，我们可以实现GeV的上型希格斯软质量，而其他质量如高吉诺质量和停止质量则较重，如1 TeV或更大。有效μ项和下型希格斯软质量之间的抵消改善了电弱对称性破缺的微调，甚至对于GeV也是如此。双线态和单线态希格斯玻色子之间的混合受到 (κ/λ) tan− 1 β 的抑制。然后，通过新的四次耦合提升，最轻的双重态希格斯质量自然达到 125 GeV。 higgsino和singlino很轻，它们的线性组合是最轻的超粒子。
We study the next-to-minimal supersymmetric standard model. We consider soft supersymmetry breaking parameters, which are induced by the mirage mediation mechanism of supersymmetry breaking. We concentrate on the mirage mediation, where the so-called mirage scale is the TeV scale. In this scenario, we can realize the up-type Higgs soft mass ofGeV, while other masses such as gaugino masses and stop masses are heavy such as 1 TeV or more. Cancellation between the effective μ-term and the down-type Higgs soft mass ameliorates the fine-tuning in the electroweak symmetry breaking even forGeV. The mixingbetween the doublet and singlet Higgsbosons issuppressed by (κ/λ) tan− 1 β. Then the lightest doublet Higgs mass naturally reaches 125 GeV lifted by the new quartic coupling. The higgsino and singlino are light and their linear combination is the lightest superparticle.
