We investigate the new contributions to the parameters gL and gR of the \( Zb\overline{b} \) vertex in a multi-Higgs-doublet model (MHDM). We emphasize that those contributions generally worsen the fit of those parameters to the experimental data. We propose a solution to this problem, wherein gR has the opposite sign from the one predicted by the Standard Model; this solution, though, necessitates light scalars and large Yukawa couplings in the MHDM.

我们研究的参数的新的贡献克大号和克- [R的的\(ZB \划线{B} \)在多希格斯-双峰模型(MHDM)顶点。我们强调这些贡献通常会恶化这些参数与实验数据的拟合。我们提出了这个问题的解决方案,其中g R与标准模型预测的符号相反;然而,这个解决方案需要 MHDM 中的轻标量和大型 Yukawa 耦合。
