- Abstract
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+-).
