Meson twist - 4 parton distributions in terms of twist - 2 distribution amplitudes at large N c
In this particular isospin combination of structure functions the contribution of twist-2 operators cancels out exactly and twist-4 contributions are dominant. It is remarkable that in the large Nc limit the twist-4 distribution function of quarks in the pion can be reduced to a convolution of twist-2 pion distribution amplitudes. 2. One can read the contribution of four-quark twist-4 operators...
متن کاملHigher Twist Distribution Amplitudes of Vector Mesons in QCD: Twist-4 Distributions and Meson Mass Corrections
We present a systematic study of twist-4 light-cone distribution amplitudes of vector mesons in QCD, which is based on conformal expansion. The structure of meson mass corrections is studied in detail. A complete set of distribution amplitudes is constructed, which satisfies all (exact) equations of motion and constraints from conformal expansion. Nonperturbative input parameters are estimated ...

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...
متن کاملHigher 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...
