CP标记的魅力衰减:相关性,现状和前景

CP-tagged charm decays: relevance, status and prospects

Guy Wilkinson

摘要:

在$ψ(3770)$共振产生的量子相关$D-\bar{D}$衰变的分析提供了独特的洞察力,如强相位差和相干因子的数量。这些参数的知识对于测量$B \to DK$衰变中的CKM角$γ$($ϕ_3$)是非常宝贵的。从CLEO-C分析结果进行了$ψ(3770)$共振在各种衰变通道的报告,并评估其后果的测定$γ$。未来的前景给出了扩展到目前的研究。

英文摘要:

The analysis of quantum-correlated $D-\bar{D}$ decays produced at the $ψ(3770)$ resonance gives unique insight into quantities such as strong-phase differences and coherence factors. Knowledge of these parameters is invaluable for measurements of the CKM-angle $γ$ ($ϕ_3$) in $B \to DK$ decays. Results from CLEO-c analyses performed at the $ψ(3770)$ resonance in a variety of decay channels are reported, and their consequences for the determination of $γ$ is assessed. Future prospects are given for extensions to the present studies.
