Vector to pseudoscalar meson radiative transitions in chiral theory with resonances
Abstract
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 sigmaV. The results are compared to the available data and to the predictions of other models.
