$\Bz\to\pip\pim\piz$ Time Dependent Dalitz analysis at BaBar

Gianluca Cavoto

摘要:

我在这里提出的Dalitz结构的中性$B$介子衰变到$\pip\pim\piz$从一个数据集的3.46亿$B \bar B$对收集在$Υ(4S)$质量质心能量由BaBar探测器在SLAC PEP-II $e^+e^-$加速器的时间相关的分析结果。未观察到显著的CP违背效应,弱角$α$的68%置信区间为[75 $^o$,152 $^o$ ]

英文摘要:

I present here results of a time-dependent analysis of the Dalitz structure of neutral $B$ meson decays to $\pip\pim\piz$ from a dataset of 346 million $B \bar B$ pairs collected at the $Υ(4S)$ center of mass energy by the BaBar detector at the SLAC PEP-II $e^+e^-$ accelerator. No significant CP violation effects are observed and 68% confidence interval is derived on the weak angle $α$ to be [75$^o$,152$^o$]
