受保护的Randall-Sundrum模型中的K和B物理

K and B Physics in the Custodially Protected Randall-Sundrum Model

Monika Blanke

摘要:

Randall-Sundrum框架为规范层次和味道问题提供了一个有吸引力的解决方案。具有扩大的保管对称性的模型与卡鲁扎-克莱因(KK)尺度低至2-3 TeV的电弱精密观测值一致,因此可以在LHC上观察到最低的KK模式。重KK规范玻色子的存在下诱导新的树水平的贡献违反味观测。我们总结了Delta F = 2和Delta F = 1扇区中K和B物理观测量的主要结果。新物理效应的特定模式可以用来区分这个模型和其他新物理框架。

英文摘要:

The Randall-Sundrum framework provides an appealing solution to both the gauge hierarchy and the flavour problem. The model with enlarged custodial symmetry is consistent with electroweak precision observables for Kaluza-Klein (KK) scales as low as 2-3 TeV, so that the lowest-lying KK modes could be observed at the LHC. The presence of the heavy KK gauge bosons induces new tree level contributions to flavour violating observables. We summarise the main results for K and B physics observables in the Delta F = 2 and Delta F = 1 sectors. The specific pattern of new physics effects can be used to distinguish this model from other new physics frameworks.
