| 摘要 | Twist-3 distribution amplitudes of the pion and kaon are studied in this paper. We calculate the first several moments for the twist-3 distribution amplitudes (phi(pi)(p,sigma) and phi(K)(p,sigma)) of the pion and kaon by applying the QCD sum rules. Our results show that (i) the first three moments of phi(K)(p) and the first two moments of phi(pi)(p) and phi(pi,K) (sigma)of the pion and kaon can be obtained with 30% uncertainty; ( ii) the fourth moment of the phi(pi)p and the second moment of the phi(K)(sigma) can be obtained when the uncertainty are relaxed to 35%; (iii) the fourth moment of the f p s can be obtained only when the uncertainty are relaxed to 40%; ( iv) we have m(0 pi)(p) = 1.10 +/- 0.08 GeV and m(0K)(p) = 1.25 +/- 0.15 GeV after including the alpha(s)-corrections to the perturbative part. These moments will be helpful for constructing the twist-3 wave functions of the pion and kaon. |
