摘要:

本文回顾了我们在两个约束超对称跷跷板模型CMSSM和NUHM中对轻子味破坏(LFV)半轻子τ衰变和μ子-电子转换的主要结果。相关的谱是由三个右手中微子$ν_{R_i}$和它们相应的SUSY伙伴${\tilde ν}_{R_i}$($i=1,2,3$)扩展的最小超对称标准模型的谱。我们使用的跷跷板机制中微子质量的产生,并选择一个参数化的机制,使我们能够将中微子数据在我们的LFV过程的分析。除了完整的单回路结果的速率,这些过程中,我们还将审查一组简单的公式,有效的大$\tan β$,这是非常有用的比较与目前的实验界限。在这些过程中的超对称性和希格斯部门的敏感性也将被讨论。这是参考文献中的一个非常简短的摘要。\cite{Arganda:2008jj}和\cite{Arganda:2007jw},读者可参考以了解更多详细信息。

英文摘要:

In this paper we review our main results for Lepton Flavour Violating (LFV) semileptonic tau decays and muon-electron conversion in nuclei within the context of two Constrained SUSY-Seesaw Models, the CMSSM and the NUHM. The relevant spectrum is that of the Minimal Supersymmetric Standard Model extended by three right handed neutrinos, $ν_{R_i}$ and their corresponding SUSY partners, ${\tilde ν}_{R_i}$, ($i=1,2,3$). We use the seesaw mechanism for neutrino mass generation and choose a parameterisation of this mechanism that allows us to incorporate the neutrino data in our analysis of LFV processes. In addition to the full one-loop results for the rates of these processes, we will also review the set of simple formulas, valid at large $\tan β$, which are very useful to compare with present experimental bounds. The sensitivity to SUSY and Higgs sectors in these processes will also be discussed. This is a very short summary of the works in Refs. \cite{Arganda:2008jj} and \cite{Arganda:2007jw} to which we refer the reader for more details.
