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.

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.

Recent developments in the theory of CP violation in the B-meson system are reviewed, with focus on the determination of sin 2β from B → J/ψ K decays, its implications for tests of the Standard Model and searches for New Physics, and the determination of γ and α from charmless hadronic B decays.

Meson System

The phenomenological description of the neutral B meson system is proposed in terms of the fundamental CP-violating observables and within a rephasing invariant formalism. This generic formalism can select the time-dependent and time-integrated asymmetries which provide the basic tools to discriminate the different kinds of possible CP-violating effects in dedicated experimental B meson facilities.

A measurement of the CP violation parameter sin 2ϕ1 based on a 29.1 fb-1 data sample recorded at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric e+ e- collider is reported. One neutral B meson is fully reconstructed as a J/ψKS, ψ(2S)KS, χc1KS, ηcKS, J/ψKL or J/ψK*0 decay and the flavor of the accompanying B meson is identified from its decay products. From the asymmetry in the distribution of the time intervals between the two B meson decay points, we determine sin 2ϕ1 = 0.99±0.14(stat) ±0.06(sys). Since this value is more than 6σ from zero, we can conclude that CP symmetry is violated in the neutral B meson system.
