论文摘要
我们表达斜参数$ s $，$ t $，$ u $，$ v $，$ w $和$ x $在三种带有三个CP-Even中性标量的BSM型号的框架中的相应混合矩阵中。我们考虑使用非标准的SM的标量扇区扩展的三种类型（i）两个真实的单线标量，（ii）一个复杂的双线和一个真实的单重标量表，以及（iii）两个复杂的双线。我们提出表达式，以便在所有中性CP-even标量都有VEV时可以使用这些表达式，或者其中一个没有任何VEV。以这种方式呈现倾斜参数的主要良好是，相应标量扇区中混合矩阵的唯一知识足以提取该特定BSM模型的倾斜参数的表达。本文还提供了一些图，以参考，显示了三个CP中性标量的质量的允许区域以及三个上述模型的三个混合角度。
We express the oblique parameters $S$, $T$, $U$, $V$, $W$, and $X$ in terms of the corresponding mixing matrices in the framework of three BSM models with three CP-even neutral scalars. We consider three types of the extension of the scalar sector of the SM with non-standard (i) two real singlet scalars, (ii) one complex doublet and one real singlet scalar, and (iii) two complex doublets. We present the expressions such that one can use these when all the neutral CP-even scalars have VEV, or one of them does not have any VEV. The principal benifit of presenting the oblique parameters in this way is, the sole knowledge of the mixing matrices in the corresponding scalar sector is enough to extract the expression of the oblique parameter of that particular BSM model. This paper also presents some plots, for reference, showing the allowed region of the masses of the three CP-even neutral scalars and the three mixing angles of the three above-mentioned models.
