Higher-Twist Distribution Amplitudes of the K Meson in QCD
We present a systematic study of twist-3 and twist-4 light-cone distribution amplitudes of the K meson in QCD. The structure of SU(3)-breaking corrections is studied in detail. Nonperturbative input parameters are estimated from QCD sum rules and renormalons. As a by-product, we give a complete reanalysis of the twist-3 and -4 parameters of the π-meson distribution amplitudes; some of the resul...
متن کاملB Meson Light-cone Distribution Amplitudes and Heavy-quark Symmetry∗
Recently systematic methods based on the QCD factorization have been developed for the exclusive B meson decays into light mesons (for other approaches see). Essential ingredients in this approach are the light-cone distribution amplitudes for the participating mesons, which constitute nonperturbative long-distance contribution to the factorized amplitudes. For the light mesons (π, K, ρ, K, etc...
متن کاملRenormalization 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 کاملTwist-3 Distribution Amplitudes of K∗ and φ Mesons
We present a systematic study of twist-3 light-cone distribution amplitudes of K and φ mesons in QCD. The structure of SU(3)-breaking corrections is studied in detail. Nonperturbative input parameters are estimated from QCD sum rules. As a by-product, we update the parameters describing the twist-3 distribution amplitudes of the ρ meson. We also review and update predictions for the twist-2 dis...
متن کاملRenormalization of B-meson distribution amplitudes
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...
