· Journal of High Energy Physics (Online)
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), χc1(3872) and ψ(2S) states are reported.
