我们考虑了超对称SU（5）和SO（10）模型中B{sub s}-B{sub s}混合的大相位的影响。在SU（5）模型中，相位的大小与τ {yields}{mu}{gamma}的分支比有关，我们发现在SU（5）模型中，相位一定很小。在SO（10）模型的情况下，这种相关性可以放松，可以得到一个大的相位。我们预测的sparticle质量范围的大型强子对撞机的这些模型，一旦最近的结果，显示大相位的证据是容纳和讨论的暗物质和异常磁矩的限制，这种分析。我们表明，费米实验室即将推出的结果将是非常有用的，以破译这些重要的大统一理论对称性。
We consider the impact of a large phase of B{sub s}-B{sub s} mixing in supersymmetric SU(5) and SO(10) models. In the models, the magnitude of this phase is correlated with the branching ratio of {tau}{yields}{mu}{gamma}, and we find that in the SU(5) model, the phase is bound to be small. In the case of SO(10) models, this correlation can be relaxed and a large phase can be obtained. We predict the sparticle mass ranges for the LHC for these models once the recent result which shows evidence of large phase is accommodated and discuss the dark matter and the anomalous magnetic moment constraints on this analysis. We show that the upcoming results of Fermilab will be very useful to decipher these important grand unified theory symmetries.
