微扰$λ$ -超对称与小$κ$ -唯象

Perturbative $λ$-Supersymmetry and Small $κ$-Phenomenology

Sibo Zheng

摘要:

对于最小的$λ$ -超对称性,它对$λ\leq 0.7$的GUT标度保持微扰.这个上限是放松时,一个人要么采取的标准,所有的耦合接近$\sim 4π$的非扰动或允许新的领域之间的中间规模的弱和大统一体的规模。我们发现,一个隐藏的$U(1)_X$规范部门与自发破碎的规模$\sim10$ TeV提高了这个界限,而不是$λ\leq1.23$。这可能会对希格斯物理学产生重大影响,例如减少涉及希格斯标量质量的微调,以及对小$κ$现象学的影响。

英文摘要:

For the minimal $λ$-supersymmetry, it stays perturbative to the GUT scale for $λ\leq 0.7$. This upper bound is relaxed when one either takes the criteria that all couplings close to $\sim 4π$ for non-perturbation or allows new fields at the intermediate scale between the weak and GUT scale. We show that a hidden $U(1)_X$ gauge sector with spontaneously broken scale $\sim10$ TeV improves this bound as $λ\leq1.23$ instead. This may induce significant effects on Higgs physics such as decreasing fine tuning involving the Higgs scalar mass, as well as on the small $κ$-phenomenology.
