The form factor of the vector meson V conversion transition into the pseudoscalar meson P and the lepton pair l+l- is presented for V=rho0,omega,phi and P=pi0,eta. Our approach is based on the chiral effective field theory with resonances. The normalized form factor for omega -> pi gamma* transition was fitted to the recent NA 60 data by varying the only free parameter sigma_V. The results are compared to the available data and to the predictions of other models.
