论文摘要
在复杂的2-higgs-doublet模型（C2HDM）中，通常选择最重的中性标量$ H_3 $的质量$ m_3 $作为派生参数。我们将一环校正调查为$ M_3 $，它们对$ H_3 $的衰减的影响。可以找到参数空间的非常微调的区域，而不是由于$ m_3 $对独立参数的特定依赖性，而不是由于减法方案而导致的。我们表明，即使是中等校正也会对$ H_3 $的衰减产生重大影响，因为这些校正可能会因领先因素而增强几倍。
In the complex 2-Higgs-Doublet Model (C2HDM), the mass $m_3$ of the heaviest neutral scalar $h_3$ is usually chosen as a derived parameter. We investigate one-loop corrections to $m_3$ and their impact on decays of $h_3$. Very fine-tuned regions of the parameter space can be found where such corrections are large, not due to subtraction schemes, but rather due to the particular dependence of $m_3$ on the independent parameters. We show that even moderate corrections can have a significant impact on decays of $h_3$, as they may be several times enhanced by leading-order factors.
