摘要：

We complete the analysis of meson resonance contributions to chiral low-energy constants of O(p(4)) by including all quark-antiquark bound states with orbital angular momentum <= 1. Different tensor meson Lagrangians used in previous work are shown to produce the same final results for the low-energy constants, once QCD short-distance constraints are properly implemented. We also discuss the possible relevance of axial-vector mesons with odd C-parity (J(PC)=1(+-)).
