英文摘要In this paper we calculate the normalization constants m(0 pi)(P) and m(0K)(P) of the twist-3 distribution amplitudes of the pion and kaon from the QCD sum rules, instead of using the equations of motion. We find that m(0 pi)(P) = 1.00 +/- 0.17GeV and m(0K)(P) = 1.46 0.23GeV after including as corrections to the perturbative part of the sum rules. They are close to the phenomenological values. For the pion case, this shows that the value obtained in QCD sum rules is only 50% of that determined by the equation of motion.
