Quark-mass and 1/Nc corrections to the vector-meson pseudoscalar-meson photon (VPγ) interaction

We analyze quark-mass and 1/N-c corrections to all of the radiative transitions between the vector-meson nonet and the pseudoscalar-meson nonet within a chiral effective Lagrangian approach. We perform fits of the available coupling constants to experimental data and discuss the corresponding approximations. In terms of five (six) coupling constants, we obtain a reasonably good description of the twelve experimental decay rates.

Automated summary

We analyze the radiative transitions between the vector-meson nonet and the pseudoscalar-meson nonet, considering quark-mass and 1/N-c corrections, using a chiral effective Lagrangian approach. By fitting the available coupling constants to experimental data, we obtain a reasonably good description of the twelve experimental decay rates.
