【 摘 要 】
In this work we propose a phenomenological Resonance Chiral Theory inspired vertex J/ψρπ, which is a basic ingredient for a description of the J/ψ phenomenology. This vertex is characterized by only one coupling constant which is computed through the analysis of the J/ψ→γπ0decay. Assuming ρ meson dominance we compute the BR(J/ψ→π0π+π-), finding a good agreement with the experimental measurement.
