Measurement of the branching fraction of J/ψ → ρπ at KEDR

Measurement of the branching fraction of J/ψ → ρπ at KEDR

Abstract We present the study of the decay J/ψ → ρπ. The results are based on of 5.2 million J/ψ events collected by the KEDR detector at the VEPP-4M collider. The branching fractions are measured to be B $$ \mathcal{B} $$ (J/ψ → ρπ) = (2.072 ± 0.017 ± 0.062) ∙ 10 −2 and B $$ \mathcal{B} $$ (J/ψ → π...
