论文摘要
直到今天，在涉及带电的瘦素的过程中还没有观察到Lepton侵犯的侵犯。因此，在理论和实验中，对其进行了搜索。在我们目前的工作中，我们研究了SU（5）Susy Gut中的稀有衰减过程的速率，例如$τ\rightarrowμγ$，发现它满足了电流的结合，并且是预计灵敏度以下的一个顺序。这给出了一个佐证的论点，即大型顶野川在肠道尺度上的影响（$λ_{tg} $）对违反风味的lept子的衰减速率，这些衰减率可在低能电动electroweak calace $ m_z $上进行研究。其次，我们讨论了$μ\ rightarroweγ$＆$τ\rightarrowμγ$的衰减率，并增加了右手中微子超级场。从中，我们使用LFV衰变的速率来研究$ \tanβ$的界限，然后研究$ \tildeχ^0 _1 $，LSP的质量。在计算中，已经使用了来自LHC的最新更新数据，中微子振荡实验和对MEG实验的分支比率的约束。
Till today lepton flavor violation has not been observed in processes involving charged leptons. Hence, a search for it is under hot pursuit both in theories and experiments. In our current work, we investigate the rates of rare decay processes such as $τ\rightarrow μγ$ in SU(5) SUSY GUT and found that it satisfies the current bound and is one order below the projected sensitivity. This gives a corroborative argument for the influence of the large top-Yukawa coupling at the GUT scale ($λ_{tG}$) on flavor violating decay rates of leptons which are investigable at low energy electroweak scale $M_Z$. Secondly, we discuss the decay rates of $μ\rightarrow e γ$ & $τ\rightarrow μγ$ in MSSM with added right handed neutrino superfields. From this, we set bounds on $\tan β$ and further, we investigate the mass of $\tildeχ^0 _1$, the LSP, using the rates of LFV decays. In the calculations, the latest updated data from LHC, neutrino oscillation experiments and constraints on branching ratios from the MEG experiment have been used.
