Abstrakt

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+-).
