$\mathit CP$ VIOLATION PARAMETERS IN ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit D}^{0}}{{\mathit K}^{*0}}$ DECAY

The parameters ${{\mathit r}}_{{{\mathit B}^{0}}}$ and ${{\mathit \delta}}_{{{\mathit B}^{0}}}$ are the magnitude ratio and strong phase difference between the amplitudes of A(${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit D}^{0}}{{\mathit K}^{*0}}$) and A(${{\mathit B}^{0}}$ $\rightarrow$ ${{\overline{\mathit D}}^{0}}{{\mathit K}^{*0}}$). The measured observables and are defined as ${{\mathit x}}_{\pm{}}$ = ${{\mathit r}}_{{{\mathit B}^{0}}}$ cos(${{\mathit \delta}}_{{{\mathit B}^{0}}}$ $\pm{}{{\mathit \gamma}}$) and ${{\mathit y}}_{\pm{}}$ = ${{\mathit r}}_{{{\mathit B}^{0}}}$ sin(${{\mathit \delta}}_{{{\mathit B}^{0}}}$ $\pm{}{{\mathit \gamma}}$) where ${{\mathit \gamma}}$ is the CKM angle ${{\mathit \gamma}}$.
"OUR EVALUATION" is provided by the Heavy Flavor Averaging Group (HFLAV). The CKM angle $\gamma $ is listed in the ${{\mathit B}^{+}}$ section for "$\mathit CP$ VIOLATION PARAMETERS IN ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit D}}{{\mathit K}^{+}}$ AND SIMILAR DECAYS."

1  Uses Dalitz plot analysis of ${{\mathit D}}$ $\rightarrow$ ${{\mathit K}_S^0}$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ , ${{\mathit K}_S^0}$ ${{\mathit K}^{+}}{{\mathit K}^{-}}$ decays coming from ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit D}}{{\mathit K}^{*}{(892)}^{0}}$ modes. The second error is the systematic contribution from the ${{\mathit D}}$ decay strong-phase inputs and from the experimental systematic uncertainties.
