摘要：

We determine the full structure of the leading (double-pole) divergences of O(p(6)) in the meson sector of chiral perturbation theory. The field theoretic basis for this calculation is described. We then use an extension of this result to determine the p6 contributions containing double chiral logarithms (L-2), single logarithms times p(4) constants (L x L-i(r)) and products of two p(4) constants (L-i(r) x L-j(r)) for F-pi, F-K/F-pi, K-l3 and K-e4 form factors. Numerical results are presented for these quantities. (C) 1998 Elsevier Science B.V. All rights reserved.
