- 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.
