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.

Loop Approximation

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.

Quantization on a surface orthogonal to a fixed lightlike vector leads to a set of second-class constraints in addition to the usual first-class constraints encountered in the conventional quantization procedure. This leads to an additional ghost field in the effective Lagrangian, but it is argued that this ghost field decouples in any computation of radiative corrections and does not enter the Becchi–Rouet–Stora identities.
