We present recent measurements of the unitarity triangle angle phi2(alpha) using B -> pi pi, B -> rho rho, and B -> rho pi decays. The measurements are based on data samples collected with the Belle and BaBar detectors at the KEKB and…

Decays of the type B --> D^{(*)} anti-D^{(*)} can be used to provide a measurement of the parameter sin2beta of the Unitarity Triangle that is complementary to the measurement derived from the mode B^0 --> J/psi K_s^0. In this document we…

We present results of a feasibility study of a model-independent way to measure the angle phi_3 of the unitarity triangle. The method involves B->DK decays where the neutral D decays to the K_S Pi+ Pi- final state, together with the sample…

We present a measurement of the unitarity triangle angle phi_3 using a Dalitz plot analysis of the K0_S pi+ pi- decay of the neutral D meson from the B+- -> D(*)K(*)+- process. The method employs the interference between D0 and D0bar to…

Quantum-correlated measurements of D0D0bar decays related to the determination of the Unitarity Triangle angle gamma/phi3 are reviewed. Measurements from the CLEO Collaboration are presented and prospects with the BES III experiment are…

We propose a new way for determining the CP violation angle $\gamma$ without any hadronic uncertainty. The suggested method is to use the two triangles formed by the decay amplitudes of $B^\pm\to (D^0,\bar D^0,D_{CP}^0)…

The decay B^0 -> DK^{*0} is well-known to provide excellent potential for a precise measurement of the Unitarity Triangle angle gamma in future experiments. It is noted that the sensitivity can be significantly enhanced by studying the…

We discuss new, theoretically clean strategies to determine the angle $\gamma$ of the unitarity triangle from $B_d\to DK_{S(L)}$, $B_s\to D\eta^{(')}, D\phi, ...$ decays, and point out that the $B_s\to DK_{S(L)}$ and $B_d\to D\pi^0,…

We point out that in decays of the type $B^- \to D^* K^-$, where the neutral $D^*$ meson is an admixture of $D^{*0}$ and $\bar{D}^{*0}$, there is an effective strong phase difference of $\pi$ between the cases that the $D^*$ is…

Constraints on the CKM angle \gamma are presented from GLW, ADS, and GGSZ analyses of B+- -> D K+- at the LHCb experiment. The branching fractions of B0 -> D0bar K+ \pi- and Bs -> D0bar K- \pi+ are also reported, measured relative to the…

In this work, I suggest a new way for determining the CKM angle $\gamma$ via B decays into a scalar/tensor meson without any hadronic uncertainty. The proposed idea makes profits of the two triangles formed by the $B^\pm\to (D^0,\bar…

The angle $\gamma$ of the Cabibbo--Kobayashi--Maskawa unitarity triangle is a benchmark parameter of the Standard Model of particle physics. A method to determine $\gamma$ from $B^{\pm} \to D K^{\pm}$ with subsequent $D \to K_{\rm…

We point out that decays of the kind $B_d\to D_\pm K_{S(L)}$ and $B_s\to D_\pm\eta^{(')},D_\pm\phi, ...$, where $D_+$ and $D_-$ denote the CP-even and CP-odd eigenstates of the neutral D-meson system, respectively, provide very efficient,…

A sensitivity study for the measurement of the CKM angle $\gamma$ from $B^0_s\rightarrow \tilde{D}^{(*)0}\phi$ decays is performed using $D$ meson reconstructed in the quasi flavour-specific modes $K\pi$, $K3\pi$, $K\pi\pi^0$, and…

We report a measurement of the CP violation parameter $\varphi_1$ obtained in a time-dependent analysis of $B^0\to\bar{D}{}^{(*)0}h^0$ decays followed by $\bar{D}{}^0\to K_S^0\pi^+\pi^-$ decay. A model-independent measurement is performed…

We point out that time dependent study of four decay modes $B^0(t)\to \Dbar K_S$, $B^0(t)\to D K_S$ $\Bbar^0(t)\to \Dbar K_S$, and $\Bbar^0(t)\to D K_S$ allows us to measure $\sin(\phi_1-\phi_2)$ - contrary to previously obtained result…

We have analyzed how much the $CP$ angles to be measured at B factories can deviate from the geometrical ones defined in unitarity triangle under the existence of new physics. The measurements are given in rephasing invariant form. If KM…

A first determination of the strong-phase difference between $D^0$ and $\bar{D^0}\to K^+K^-\pi^+\pi^-$ is performed using $e^+e^-\to\psi(3770)\to D\bar{D}$ data collected by the BESIII detector corresponding to an integrated luminosity of…

I examine a possibility to extract the angle $\gamma$ of the Cabibbo-Kobayashi-Maskawa unitarity triangle by the inclusive $B \to X_d \l^+ \l^- $ decay. An independent information for the angle is expected from the non-trivial contribution…

I review several methods for determining the CKM phases $\alpha \equiv \phi_2$ and $\gamma \equiv \phi_3$ through CP asymmetry measurements in hadronic B decays. The current status of these measurements and the near future feasibility of…
