Impact of gamma-V vertex corrections on the V-P-gamma transition form   factors
  The aim of this paper is to present an effective field theory description of the conversion transition of the vector meson V into the pseudoscalar P and the lepton-pair l+l-. The normalized form factor for omega to pi^0 gamma^ast transition is presented and compared to the available data and to the predictions of other models.
