The data were collected with the LHCb experiment during 2016-2018, corresponding to an integrated luminosity of 5.4 fb(-1). The B-s(0) mesons are reconstructed via the decays B-s(0) -> J/psi phi and B-s(0) -> D-s(-)pi(+). The ratio of branching fractions is measured to be B(B-c(+) -> B-s(0)pi(+))/B(B-c(+) -> J/psi pi(+)) = 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. %K B Physics %K Branching fraction %K Flavour Physics %K Hadron-Hadron Scattering %R 10.1007/JHEP07(2023)066 %U https://arxiv.org/abs/2210.12000 %U https://doi.org/10.1007/JHEP07(2023)066 %P 066-19pp
