最近BaBar与Belle国际合作组对弱衰变Bd→J ψKS 中的CP破坏测量结果似乎暗示有新物理存在于B0d B0d 混合 .为此给出一个模型无关的分析 ,以说明新物理对标准模型结果的可能修正 .特别强调 ,即使实验证明Bd→J ψKS 中的CP破坏效应与标准模型的预言相符 ,仍然有可能存在新物理 . Recently BaBar and Belle’s International Collaboration on CP damage measurements in weakly decayed Bd → J ψKS seem to imply that new physics exists in the B0d B0d mixture. To do so, a model-independent analysis is presented to illustrate the impact of the new physics on the results of the standard model May be amended.In particular, it is emphasized that even though experiments show that the CP destruction effect in Bd → J ψKS agrees with the prediction of the standard model, there is still the possibility of new physics.
