我们考虑了有效的ii型双希格斯双重态模型,该模型起源于狄拉克高介子模型,在规范扇区具有扩展的超对称,它在最简单的实现中是自动对准的。我们表明,提高扩展超对称的尺度并包括量子修正实际上改善了对准。利用一种有效的场论方法,包括新的阈值修正和双环RGEs,加上低能理论中希格斯质量的双环修正,我们研究了希格斯质量和其他实验约束对超伴子尺度的影响。我们对比了最小狄拉克高规模型的结果,其中对准是自动的,与hMSSM和MRSSM,其中对准不是自动的,也为新模型提供了hMSSM启发的分析。
We consider the effective type-II two-Higgs doublet model originating from Dirac gaugino models with extended supersymmetry in the gauge sector, which is automatically aligned in the simplest realisations. We show that raising the scale at which the extended supersymmetry is manifest and including quantum corrections actually improves the alignment. Using an effective field theory approach including new threshold corrections and two-loop RGEs, plus two-loop corrections to the Higgs mass in the low-energy theory, we study the implications from the Higgs mass and other experimental constraints on the scale of superpartners. We contrast the results of the minimal Dirac gaugino model, where alignment is automatic, with the hMSSM and the MRSSM, where it is not, also providing an hMSSM-inspired analysis for the new models.
