关联D0-D0bar衰变的模型无关分析中的粲混合

Charm mixing in the model-independent analysis of correlated D0-D0bar decays

Alex Bondar, Anton Poluektov, Vitaly Vorobiev

摘要:

我们研究了粲混合对模型无关的伽马测量的影响,使用Dalitz图分析从B+->DK+过程的三体D衰变,并表明在分析的所有阶段忽略混合是安全的,直到亚度精度水平。我们还发现,在e+e碰撞中D 0-D 0 * 系统的相干产生中,粲混合效应增强,并提出了一种与模型无关的方法来测量粲工厂时间积分Dalitz分析中的粲混合参数.

英文摘要:

We investigate the impact of charm mixing on the model-independent gamma measurement using Dalitz plot analysis of the three-body D decay from B+->DK+ process, and show that ignoring the mixing at all stages of the analysis is safe up to a sub-degree level of precision. We also find that in the coherent production of D0-D0* system in e+e- collisions, the effect of charm mixing is enhanced, and propose a model-independent method to measure charm mixing parameters in the time-integrated Dalitz analysis at charm factories.
