用振幅比值方法预言中性粲介子衰变到CP本征态的CP不对称性(英文)

CP Asymmetry Prediction for Neutral Charmed Meson Decays into CP Eigenstates by Using Amplitude Ratios

用振幅比之方法计算了中性粲介子衰变到CP本征态的CP不对称性.计算了时间相关和时间积分的CP不对称性.结果表明,时间积分的CP不对称参数约为千分之一的量级.还讨论了在BESⅢ和B工厂上实验检验的可能性.

CP asymmetries for neutral charmed meson decays into CP eigenstates are calculated by using amplitude ratios. The formulas and numerical results are presented. The impact on experiments is briefly discussed.
