Twist-3 Distribution Amplitudes of K∗ and φ Mesons
نویسنده
چکیده
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 distribution amplitudes of ρ, K and φ. [email protected] [email protected]

Higher Twist Distribution Amplitudes of Vector Mesons in QCD: Formalism and Twist Three Distributions
We present a systematic study of twist three light-cone distribution amplitudes of vector mesons in QCD, which is based on conformal expansion and takes into account meson and quark mass corrections. A complete set of distribution amplitudes is constructed for ρ, ω, K and φ mesons, which satisfies all (exact) equations of motion and constraints from conformal expansion. Nonperturbative input pa...
متن کاملTHE EUROPEAN PHYSICAL JOURNAL A Twist-3 light-cone distribution amplitudes of the scalar mesons within the QCD sum rules and their application to the B → S transition form factors
We investigate the twist-3 light-cone distribution amplitudes (LCDAs) of the scalar mesons a0, K∗ 0 and f0 within the QCD sum rules. The QCD sum rules are improved by a consistent treatment of the sizable s-quark mass effects within the framework of the background field approach. Adopting the valence quark component (q̄1q2) as the dominant structure of the scalar mesons, our estimation for their...
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 کاملTheoretical Update of Pseudoscalar Meson Distribution Amplitudes of Higher Twist: The Nonsinglet Case
We discuss the two and three particle light-cone distribution amplitudes (DAs) of pseudoscalar nonsinglet mesons of twist 3 and 4. Using nonlocal operator identities and conformal expansion, we derive closed expressions for several DAs. We also include meson-mass corrections which prove to be dominant in the twist 4 DAs of K and η mesons. Explicit parametrizations for the DAs of π, K and η meso...
متن کاملHigher-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...
