AI总结:

本文介绍了BESIII实验为测量CKM角$γ$提供的关键输入,指出利用其量子关联数据样本可高度抑制来自粲区的$γ$不确定度,从而辅助检验CKM矩阵幺正性与寻找新物理。

摘要:

CKM角$γ$对于检验CKM矩阵的幺正性及寻找新物理至关重要。在LHCb和Belle-II等B工厂中,$γ$可通过$b\ o u$与$b\ o c$间的干涉提取。确定$γ$还需来自粲工厂(如BESIII实验)的强参数信息。利用BESIII收集的量子关联数据样本,来自粲区的$γ$不确定度可被高度抑制。

英文摘要:

The CKM angle $γ$ is important for testing the unitarity of the CKM matrix and searching for new physics. $γ$ can be extracted by the interference between $b\to u$ and $b\to c$ in the B factory such as LHCb and Belle-II. Determining $γ$ also needs strong parameter information from the charm factory, such as the BESIII experiment. With quantum-correlated data samples collected at BESIII, the $γ$ uncertainties from the charm sector can be highly suppressed.
