摘要：
We complete the analysis of meson resonance contributions to chiral low-energy constants of O(p4) 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 (JPC=1+-).
