论文摘要

我们向标准模型提供了一个扩展名$ u(1)_ {x} $,该模型重现了由实验确定的Lepton质量结构。在充电领域,我们引入了尺寸$ n = 7 $的有效运营商,以产生电子的质量,该电子的质量由于$ x $电荷而在树级别为null。在中立部门,我们通过反seesaw机制增加了三个无菌右中微子和三个主要中微子,以生成左手中微子的质量结构。该模型无参数拟合已知的质量特征值$ m_ {e},\,m_μ,\,m_τ$,并与中微子振荡数据的全局分析进行了全局分析。根据调整自由参数,我们获得了Yukawa耦合集的允许区域。

We present an extension $U(1)_{X}$ to the Standard Model that reproduces the lepton mass structures determined by the experiments. In the charged sector, we introduced effective operators of dimension $n = 7$ to generate the mass of the electron, which is null at tree-level due to the $X$ charge. In the neutral sector, we added three sterile right-handed neutrinos and three Majorana neutrinos to generate the mass structure for the left-handed neutrinos, by the inverse seesaw mechanism. The model free parameters were fitted with the known mass eigenvalues $m_{e},\,m_μ,\,m_τ$, and with the most recent results of a global analysis of the data from neutrino oscillation. From the adjustment of the free parameters, we obtained allowed regions for the Yukawa coupling set.
