Abstract
Further distribution of this work must maintain attribution to the author(s) and the published article's title, journal citation, and DOI. Using pp collision data collected by LHCb at center-of-mass energies √s = 7 TeV and 8 TeV, corresponding to an integrated luminosity of 3fb⁻¹, the ratio of the branching fraction of the B[subscript c]⁺→ψ(2S)π⁺ decay relative to that of the B[subscript c]⁺→J/ψπ⁺ decay is measured to be 0.268±0.032(stat)±0.007(syst)±0.006(BF). The first uncertainty is statistical, the second is systematic, and the third is due to the uncertainties on the branching fractions of the J/ψ→μ⁺μ⁻ and ψ(2S)→μ⁺μ⁻ decays. This measurement is consistent with the previous LHCb result, and the statistical uncertainty is halved.
