论文摘要
采用了自下而上的方法来确定与当前实验测量相符的风味模型。带电的费米昂质量层次结构表明，只有Yukawa的最高术语才能在术语水平上存在。拉格朗日（Lagrangian）的风味对称性，包括费米子动力学术语和最高的Yukawa，然后是U（2）和U（3）因子的组合。考虑到特定的弹性场，出现了较轻的带电费米昂和活跃的中微子肿块以及夸克和Lepton混合物。研究了相关的现象学，该模型在夸克和Lepton领域都具有最小风味的风味保护。还研究了促进弹药为动态场，还研究了相关的标量电势，并确定了最小值，从而正确复制了费米昂的质量和混合。
A bottom-up approach has been adopted to identify a flavour model that agrees with present experimental measurements. The charged fermion mass hierarchies suggest that only the top Yukawa term should be present at the renormalisable level. The flavour symmetry of the Lagrangian including the fermionic kinetic terms and only the top Yukawa is then a combination of U (2) and U(3) factors. Lighter charged fermion and active neutrino masses and quark and lepton mixings arise considering specific spurion fields. The associated phenomenology is investigated and the model turns out to have almost the same flavour protection of the Minimal Flavour Violation, in both quark and lepton sectors. Promoting the spurions to be dynamical fields, the associated scalar potential is also studied and a minimum is identified such that fermion masses and mixings are correctly reproduced.
