SU(3) breaking in K and K* distribution amplitudes.

Ball, P. and Boglione, M. (2003) 'SU(3) breaking in K and K* distribution amplitudes.', Physical review D : particles and fields., 68 . 094006.


We calculate the decay couplings and first two Gegenbauer moments of the leading twist light-cone distribution amplitudes of K and K* from QCD sum rules, including NLO perturbative effects.
