Radiative Decays involving a0(980) and f0(980) in the Vector Meson Dominance Model
/ Authors
/ Abstract
We summarize some features of the vector meson dominance model which was recently proposed for studying radiative decays involving the scalar mesons. Using the experimental values of {Gamma}(a{sub 0} {yields} {gamma}{gamma}), {Gamma}(f{sub 0} {yields} {gamma}{gamma}) and {Gamma}({phi} {yields} a{sub 0} {gamma}) as inputs, we show that the model predicts a large hierarchy between {Gamma}(a{sub 0} {yields} {omega}{gamma}) and {Gamma}(a{sub 0} {yields} {rho}{gamma}) as well as between {Gamma}(f{sub 0} {yields} {omega}{gamma}) and {Gamma}(f{sub 0} {yields} {rho}{gamma}).
