AI总结:

本文针对含最高至 dim-6 高维玻色算符的 2HDM,利用 S 矩阵微扰幺正性导出算符限制,并指出其可增大标量粒子矢量玻色子融合截面。

摘要:

我们研究双希格斯二重态模型(2HDM)中由最高至 dim-6 的高维玻色算符给出的微扰幺正性界限。这些算符带来超越标准模型的新物理。我们指出,与树级 2HDM 相比,此类算符可使标量粒子在矢量玻色子融合道中产生更大的截面。通过确保 S 矩阵的幺正性,我们获得了 2HDM 中若干最高至 dim-6 的玻色算符所受的限制。

英文摘要:

We study the perturbative unitarity bound given by higher dimensional bosonic operators up to dim-6 for the two-Higgs-doublet model (2HDM). They lead to new physics beyond the Standard Model. We point out that such operators can lead to a larger cross-section in the vector boson fusion channels for the scalars, compared to the tree-level 2HDM. We have obtained limits on a few bosonic operators up to dim-6 for 2HDM, by ensuring unitarity of the S-matrix.
