研究通过高能一致性约束补充实验限制,定义2HDM有效场论允许的参数空间。

摘要:

我们研究了在包含最高维算符至六维的情况下,perturbative unitarity要求如何限制2HDM的参数空间。我们证明了这些算符可以增强向量玻色子融合相对2HDM的标量产生截面。利用S矩阵unitarity,我们对几种六维bosonic算符设定了界限。我们还发现,某些在电弱精度数据中受约束较差的T参数违反算符的Wilson系数的盲方向,在考虑unitarity约束时可以被部分排除。这些结果展示了高能一致性如何补充实验限制,在定义2HDM有效场论允许的参数空间中发挥作用。

英文摘要:

We study how the requirement of perturbative unitarity restricts the parameter space of the two-Higgs-doublet model (2HDM) when higher-dimensional operators up to dimension six are included. We demonstrate that such operators can enhance scalar production cross sections in vector boson fusion relative to 2HDM. Using S-matrix unitarity, we place bounds on several dimension-six bosonic operators. We also find that certain blind directions in the Wilson coefficients of T-parameter violating operators which are poorly constrained by electroweak precision data can be partially excluded when unitarity constraints are taken into account. These results demonstrate how high-energy consistency can complement experimental limits in defining the allowed parameter space of 2HDM effective field theory.
