论文摘要
这项工作通过新型的精确参数化的镜头分析了标准模型的一系列扩展。该参数化特别适合分析具有非单身混合矩阵的标准模型的扩展，例如具有矢量样费米子或右手中微子的模型。该参数化的有用性是通过两个示例模型激励的：a）添加$ n_u $ up和$ n_d $ down singlet vector矢量夸克和b）标准模型的标准模型，并添加了$ n_r $右手中微子。
This work analyses a class of extensions of the Standard Model through the lens of a novel exact parameterisation. This parameterisation is specially suitable to the analysis of extensions of the Standard Model with non-unitary mixing matrices, like models with vector-like fermions or right-handed neutrinos. The usefulness of this parameterisation is motivated with two example models: A) Standard Model with the addition of $n_u$ up and $n_d$ down singlet vector-like quarks and B) Standard Model with the addition of $n_R$ right-handed neutrinos.
