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.
我们考虑源自规范扇区具有扩展超对称性的狄拉克超对称规范子模型的有效II型双希格斯二重态模型，该模型在最简单的实现中自动对齐。我们表明，提高扩展超对称性显现的尺度并纳入量子修正实际上会改善对齐情况。使用一种有效场论方法，包括新的阈值修正和两圈重整化群方程，再加上低能理论中希格斯质量的两圈修正，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。我们将对齐是自动的最小狄拉克超对称规范子模型的结果与对齐不是自动的hMSSM和MRSSM的结果进行对比，还对新模型提供了一种受hMSSM启发的分析。
