Ball, Patricia and Braun, Vladimir and Lenz, Alexander (2006) 'Higher-twist distribution amplitudes of the K meson in QCD.', Journal of high energy physics., 2006 (05). 004.
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. Non-perturbative 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 results differ from those usually quoted in the literature.
