- The ratio of branching fractions of B+c → B0sπ+ and B+c → J/ψπ+ decays is measured with proton-proton collision data of a centre-of-mass energy of 13TeV. The data were collected with the LHCb experiment during 2016-2018, corresponding to an integrated luminosity of 5.4 fb-1. The B0s mesons are reconstructed via the decays B0s → J/ψφ and B0s → D‾sπ+. The ratio of branching fractions is measured to be B (B+c → B0sπ+) /B (B+c → J/ψπ+) = 91 ± 10 ± 8 ± 3 where the first uncertainty is statistical, the second is systematic and the third is due to the knowledge of the branching fractions of the intermediate state decays.
