C2.00002: phi2 and phi3 related CP Volation Measurements Invited Speaker: We present the recent results from BaBar and Belle experiments on the measurements of the angles, $\phi_2(\alpha)$ and $\phi_3(\gamma)$, in the CKM unitarity triangle. The results include measurements of $CP$ violation in charmless $B$ decays such as $B^0 \to \pi^+\pi^-$, and determination of $\phi_3(\gamma)$ based on $B \to DK$ Dalitz plot analysis.

C2.00003: Measurements of the CKM angle $\beta$ with charmonium and penguin $B$ decays Invited Speaker: We report on recent measurements of the CKM angle $\beta$ with samples of $B$ decays to charmonium final states and charmless final states. The former are dominated by tree decay amplitudes whereas the latter are dominated by penguin-loop amplitudes. The standard model predicts the time-dependent mixing-induced CP-asymmetries in these two different types of decays to be the same in leading order and to be proportional to $\sin 2\beta$. A comparison of the measured values for $\sin 2\beta$ obtained from charmonium and penguin decays will be presented. [Preview Abstract] |
