本文研究了最近报道的Tevatron上类号双μ子不对称性的3.2σ标准模型偏差的新物理意义。假设新物理只进入Bsmixing振幅,我们探讨了一般新物理,一般超对称(SUSY)模型和SUSY SU(5)的含义。在超对称SU(5)的情况下,我们利用大统一理论尺度之间的关系slepton和夸克软质量预测率轻子味破坏(LFV)。τ→μγ的预测速率在未来的Super-B工厂中是可以检测到的。
We study the new physics (NP) implications of the recently reported 3.2σ Standard Model (SM) deviation in the like-sign dimuon asymmetry at the Tevatron. Assuming that new physics only enters the Bsmixing amplitude we explore the implications for generic new physics, general supersymmetric (SUSY) models and also SUSY SU(5). In the case of SUSY SU(5) we exploit the GUT scale relationship between slepton and squark soft masses to predict rates for lepton flavour violation (LFV). The predicted rates for τ→μγ are found to be detectable at future Super-B factories.
