Abstract
We formulate a parity-invariant chiral Lagrangian which includes nonlinearly transforming vector mesons but no axial-vector mesons. It is gotten by a simple substitution from the Lagrangian involving a linearly transforming vector and axial-vector multiplet. This feature makes it easy to apply in the case when a gauged Wess-Zumino term is present, and we discuss the prototype anomalous strong decay ω→3π. .AEKeywords
