Determination of the CKM angle $\gamma$ with $B^{0} \rightarrow D(h^{+}h^{-})K*^{0}$ decays

A study to measure the CKM unitarity-triangle angle $\gamma$ with $B^0 \to D K^{*0}$ decays is presented. The $D$ meson (either \Dz or \Dzb) is reconstructed in the two-body final states $\Kpm\pimp$, \KpKm, and \pipi, and the \Kstarz in the self-tagging final state $\Kp\pim$. Detailed analysis of th...

description A study to measure the CKM unitarity-triangle angle $\gamma$ with $B^0 \to D K^{*0}$ decays is presented. The $D$ meson (either \Dz or \Dzb) is reconstructed in the two-body final states $\Kpm\pimp$, \KpKm, and \pipi, and the \Kstarz in the self-tagging final state $\Kp\pim$. Detailed analysis of the signal and background are performed with the latest simulation of the LHCb experiment. The statistical uncertainty on $\gamma$ is estimated to be in the range 15$^{\circ}$ - 25$^{\circ}$, for an integrated luminosity of 2~fb$^{-1}$, depending on the unknown value of the strong phase difference in \Bz decays, \dB, and other hadronic parameters, that can be evaluated from data.
