RADIATIVE PI-RHO AND PI-OMEGA TRANSITION FORM-FACTORS IN A LIGHT-FRONT CONSTITUENT QUARK-MODEL

The form factors of the pi rho and pi omega radiative transitions are evaluated within a light-front constituent quark model, using for the first time the eigenfunctions of a light-front mass operator reproduci ng the meson mass spectrum and including phenomenological Dirac and Pa uli quark form factors in the one-body electromagnetic current operato r. The sensitivity of the transition form factors both to the meson wa ve functions and to the constituent quark form factors is illustrated. It is shown that the measurement of the pi rho and pi omega radiative transitions could help in discriminating among various models of the meson structure.
