具有最小味道破坏的MSSM中的mu-->e+gamma衰变速率

mu-->e+gamma Decay Rate in the MSSM with Minimal Flavour Violation

M. Davidkov, D. I. Kazakov

摘要:

的分支比的μ-->e+ γ衰变的MSSM中的最小味违反的框架计算的MSSM参数空间的各个区域。轻子味破坏通过PMNS混合矩阵。与实验数据相比,对tan β的依赖性进行了研究。结果主要取决于混合角theta_{13}。对这种衰变的观测将作为超越SM的新物理学的一种表现。

英文摘要:

The branching ratio for the mu-->e+gamma decay in the framework of the minimal flavour violation in the MSSM is calculated for various regions of the MSSM parameter space. The lepton flavour violation goes through the PMNS mixing matrix. The dependence on tanbeta is studied in comparison with experimental data. The results crucially depend on the mixing angle theta_{13}. Observation of this decay would serve as a manifestation of new physics beyond the SM.
