چکیده
We summarize a recent calculation of the evolution kernels of the two-particle B-meson distribution amplitudes φ+ and φ− taking into account three-particle contributions. In addition to a few phenomenological comments, we give as a new result the evolution kernel of the combination of three-particle distribution amplitudes ΨA −ΨV and confirm constraints on φ+ and φ− derived from the light-quark equation of motion.

Renormalization of B-meson distribution amplitudes
We summarize recent calculations concerning the evolution kernels of the two-particle B-meson distribution amplitudes φ + and φ − taking into account three-particle contributions, as well as the evolution kernel of the combination of three-particle distribution amplitudes Ψ A − Ψ V. We exploit these results to confirm constraints on φ + and φ − derived from the light-quark equation of motion.
متن کاملAn Analysis of the Inclusive Decay Υ(1S) → η′X and Constraints on the η′-Meson Distribution Amplitudes
We calculate the η′-meson energy spectrum in the decay Υ(1S) → η′ggg → η′X in the leading-order perturbative QCD in the static quark limit for the Orthoquarkonium. Our principal result is the extraction of parameters of the η′g∗g effective vertex function (EVF) involving a virtual and a real gluon from the available data on the hard part of the η′-meson energy spectrum. The perturbative QCD bas...
متن کاملVector-pseudoscalar two-meson distribution amplitudes in three-body B meson decays
We study three-body nonleptonic decays B → V V P by introducing two-meson distribution amplitudes for the vector-pseudoscalar pair, such that the analysis is simplified into the one for two-body decays. The twist-2 and twist-3 φK two-meson distribution amplitudes, associated with longitudinally and transversely polarized φ mesons, are constrained by the experimental data of the τ → φKν and B → ...
متن کاملB meson light-cone distribution amplitudes in the heavy-quark limit
We investigate the B meson light-cone distribution amplitudes in the heavyquark limit which are relevant for the QCD factorization approach for the exclusive B meson decays. We derive exact relations between twoand three-particle distribution amplitudes from the QCD equations of motion and heavy-quark symmetry constraint. As solution of these relations, we give representations for the quark-ant...
متن کاملModelling light-cone distribution amplitudes from non-relativistic bound states
We calculate light-cone distribution amplitudes for non-relativistic bound states, including radiative corrections from relativistic gluon exchange to first order in the strong coupling constant. We distinguish between bound states of quarks with equal (or similar) mass, m1 ∼ m2, and between bound states where the quark masses are hierarchical, m1 ≫ m2. For both cases we calculate the distribut...
