Twist-4 distribution amplitudes of the K* and phi mesons in QCD.

Ball, Patricia and Braun, Vladimir and Lenz, Alexander (2007) 'Twist-4 distribution amplitudes of the K* and phi mesons in QCD.', Journal of high energy physics., 2007 (08). 090.


We present a systematic study of twist-4 light-cone distribution amplitudes of the K ∗ and φ meson in QCD. The structure of SU(3)-breaking corrections is studied in detail. Non-perturbative input parameters are estimated from QCD sum rules and a renormalon based model. As a by-product, we give a complete reanalysis of the parameters of the twist-4 ρ-meson distribution amplitudes.
