Description
Two recent results on the time-dependent CP violation in $b \to c \overline{u} d$ transitions are discussed. The first one is joint Belle and BaBar analysis of the $\overline{B}{}^0\to D^0_{CP} h^0$ decays, where $h^0$ is a light unflavored meson and $D^0$ meson is reconstructed in a CP specific final state. The second one is analysis of the $\overline{B}{}^0\to D^0 h^0$, $D^0 \to K_S^0\pi^+\pi^-$ decays at Belle. Time-dependent analysis of the $b \to c \overline{u} d$ transitions provides the most precise measurement of the $\cos{2\varphi_1}$, and it is almost free of the hadronic uncertainties. It also provides an approach for measurement of the $\sin{2\varphi_1}$, complimentary to the $b \to c\overline{c}s$ analysis. Future analysis of the $b \to c \overline{u} d$ transitions with large data sets of LHCb and Belle II experiments will provide an essential test of the Standard Model.
