低尺度跷跷板mSUGRA模式中的带电LFV

Charged LFV in a low-scale seesaw mSUGRA model

Amon Ilakovac, Apostolos Pilaftsis

摘要:

在TeV尺度的单重中微子扩展的MSSM框架下,研究了最小超引力边界条件(mSUGRA)对最近提出的轻子味破坏(LFV)超对称机制的影响.我们发现,考虑mSUGRA边界条件可以使衰变为三个带电轻子的μ子和τ子的分支比增加5倍,而相应的光子衰变的分支比几乎保持不变.

英文摘要:

We investigate the influence of the boundary conditions of minimal supergravity (mSUGRA) on the supersymmetric mechanism for lepton flavour violation (LFV) proposed recently [1], within the framework of the MSSM extended by TeV-scale singlet heavy neutrinos. We find that the consideration of the mSUGRA boundary condition may increase the branching ratios of the muon and tauon decaying into three charged leptons by up to a factor of 5, whereas the corresponding branching ratio for their photonic decays remains almost unchanged.
