Scalar and vector meson exchange in

  title={Scalar and vector meson exchange in},
  author={Rafel Escribano},
The scalar contributions to the radiative decays of light vector mesons into a pair of neutral pseudoscalars, V → P 0P 0γ, are studied within the framework of the Linear Sigma Model. This model has the advantage of incorporating not only the scalar resonances in an explicit way but also the constraints required by chiral symmetry. The experimental data on φ → π0π0γ, φ → π0ηγ, ρ → π0π0γ and ω → π0π0γ are satisfactorily accommodated in our framework. Theoretical predictions for φ → K0K̄0γ, ρ → π0… CONTINUE READING
