A. E. Cárcamo Hernández, Jonatan Vignatti, Alfonso Zerwekh

摘要:

我们构建了两个可行的扩展SM与一个重矢量的基本$SU\left( 2\right) _{L}$表示和9 SM单线态标量场,符合目前的SM费米子质谱和费米子混合参数。小质量的活动中微子产生于辐射跷跷板机制在一个回路水平介导的中性分量的重矢量以及左手Majorana中微子。所提出的模型预测率带电轻子味违反过程的范围内即将到来的实验。

英文摘要:

We construct two viable extensions of the SM with a heavy vector in the fundamental $SU\left( 2\right) _{L}$ representation and nine SM singlet scalar fields, consistent with the current SM fermion mass spectrum and fermionic mixing parameters. The small masses for the active neutrinos are generated from radiative seesaw mechanism at one loop level mediated by the neutral components of the heavy vector as well as by the left handed Majorana neutrinos. The proposed models predicts rates for charged lepton flavor violating processes within the reach of the forthcoming experiments.
