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.

B-meson light-cone distribution amplitudes are discussed in these lectures in the framework of HQET. The evolution equation for the leading-twist distribution amplitude is derived in one-loop approximation. QCD sum rules for distribution amplitudes are discussed.

Babar Detector

We report on a preliminary measurement of time-dependent CP-violating asymmetries in [Formula: see text] and [Formula: see text] decays recorded by the BABAR detector at the PEP-II asymmetric B Factory at SLAC. The data sample consisted of 9.0 fb-1 collected at the ϒ(4S) resonance and 0.8 fb-1 off-resonance. One of the pair of neutral B mesons produced at the ϒ(4S) was fully reconstructed, while the flavor of the other neutral B meson was tegged at the time of its decay. The value of the asymmetry amplitude, sin 2β, was determined from a maximum likelihood fit to the time distribution of 120 tegged candidates to be sin 2β=0.12±0.37( stat. )± 0.09( syst. ) (preliminary).
