N2 - 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 (J/ψ → ρπ) = (2.072 ± 0.017 ± 0.062) ∙ 10−2 and B (J/ψ → π + π − π 0) = (1.878 ± 0.013 ± 0.051) ∙ 10−2, where the first uncertainties are statistical and the second systematic. Our results are more precise than the previous relative measurements.
