摘要

我们给出了在双希格斯-双重态模型和标准模型的单重态扩展中，轻cp -偶希格斯玻色子衰变成四个费米子的部分衰减宽度的次一级计算。计算中采用了不同的重整化方案，并在分析工具predicy4f中实现。一些关于希格斯->4费米子衰变宽度的样本结果说明了修正如何减少对重整化尺度和方案选择的依赖。

Electroweak corrections in the Two-Higgs-Doublet Model and Singlet Extension of the Standard Model

We present the next-to-leading-order calculation of the partial decay widths of light CP-even Higgs bosons decaying into four fermions in the Two-Higgs-Doublet Model and a Singlet Extension of the Standard Model. Different renormalization schemes are applied in the calculation, which is implemented into the analysis tool PROPHECY4F. Some sample results on the Higgs->4fermions decay widths illustrate how the corrections reduce the dependence on the renormalization scale and the choice of the scheme.
