Leading-twist pion and kaon distribution amplitudes from the QCD instanton vacuum

Abstract: Twist-3 distribution amplitudes of the pion and kaon are studied in this paper. We calculate the fist several moments for the twist-3 distribution amplitudes (φ π p,σ and φ K p,σ) of the pion and kaon by applying the QCD sum rules. Our results show that, (i) the first three moments of φ K p and the first two moments of φ π p and φ π,K σ of the pion and kaon can be obtained with 30% uncertainty; (ii) the fourth moment of the φ π p and the second moment of the φ K σ can be obtained when the uncertainty are relax… Show more

“…For the kaon case, the odd moments are nonzero due to the flavor SU(3) symmetry breaking effects. We again note that the sign of Gegenbauer and ξ moments are the same between our LFQM and χQM [17] predictions but different from QCDSR [9] and DSE [22] predictions.…”

“…We also should note for the same reason that our LFQM results are in good agreement with DSE results in the chiral-symmetry limit of φ σ 3;π (x). In Table III, we list the calculated Gegenbauer-and ξ-moments of the pseudotensor twist-3 kaon φ σ 3;K (x) obtained from the Gaussian wave function with linear and HO potential models and PL wave function and compare them with other model estimates [9,17,22]. For the kaon case, the odd moments are nonzero due to the flavor SU(3) symmetry breaking effects.…”

“…This value is well consistent with those from the chiral quark and instanton models in Refs. [8,26]: k 2 T π ≈= (0.20 ∼ 0.23) GeV 2 . All the numerical results for QC, MC, and m 2 0 are summarized for some different T values in Table I.…”
