摘要:

本文在超对称经济3-3-1模型框架下研究了荷轻子味破坏(cLFV)衰变$τ-> μγ$,$τ-> 3μ$和$Z->μτ$.给出了这些衰变的分支比(BR)的解析公式。我们假设在左手和右手slepton扇区中都存在轻子味破坏源。这导致cLFV衰减速率的强烈增强。我们还表明,LFV源对左手Slepton扇区的cLFV衰减率的影响大于右手Slepton扇区。通过数值计算,我们证明了在小$\tan γ$的极限下,所考虑的模型包含的slepton的相对轻质量谱满足目前LFV过程的实验界.同时还研究了偶极子和偶极子算符之间的相互作用。

英文摘要:

In this work, we study the charged lepton flavor violating (cLFV) decays $τ-> μγ$, $τ-> 3μ$ and $Z->μτ$ in the framework of the Supersymmetric economical 3-3-1 model. Analytic formulas for branching ratios (BR) of these decays are presented. We assume that there exist lepton flavor violation (LFV) sources in both right- and left-handed slepton sectors. This leads to the strong enhancement of cLFV decay rates. We also show that the effects of the LFV source to the cLFV decay rates in the left-handed slepton sector are greater than those in the right- handed slepton sector. By numerical investigation, we show that the model under consideration contains the relative light mass spectrum of sleptons which satisfies the current experimental bounds on LFV processes in the limit of small $\tan γ$. The interplay between monopole and dipole operators also was studied.
