The decays B⁺ → J/ψπ⁺π^–K⁺ are studied using a data set corresponding to an integrated luminosity of 9 fb^–1 collected with the LHCb detector in proton-proton collisions between 2011 and 2018. Precise measurements of the ratios of branching fractions with the intermediate ψ₂(3823), χ_c1(3872) and ψ(2S) states are reported.
