The Future

In this paper, we study the [Formula: see text] form-factors with the light-cone QCD sum rules, where the B-meson light-cone distribution amplitudes are used. In calculations, we observe that the line-shapes of the B-meson light-cone distribution amplitude ϕ+(ω) have significant impacts on the values of the form-factors, and expect to obtain severe constraints on the parameters of the B-meson light-cone distribution amplitudes from the experimental data in the future.

We present recent results on CP violation in the B meson system from the BABAR experiment at the PEP II asymmetric e+e- collider. We discuss the study of CP violation in B-mixing and present measurements of unitarity-triangle angles α, β, and constraints on γ.

Recent BaBar results on rare B decays involving flavor changing neutral currents are presented. New measurements of the CP asymmetries in b→sγ and B→K*γ decays are reported as well as B→K(*)l+l- and b→sl+l- branching ratio measurements. The data sample comprises [Formula: see text] decays collected with the BaBar detector at the PEP-II e+e- storage ring.

The B-meson system provides many strategies to perform stringent tests of the Standard-Model description of CP-violation. In this brief review, we discuss implications of the currently available B-factory data on the angles α, β and γ of the unitarity triangle, emphasize the importance of Bsstudies at hadronic B experiments, and discuss new, theoretically clean strategies to determine γ.
