Abstract

The ratio of branching fractions of B_c⁺→B_s⁰π⁺ and B_c⁺→J/ψπ⁺ decays is measured with proton-proton collision data of a centre-of-mass energy of 13 TeV. The data were collected with the LHCb experiment during 2016–2018, corresponding to an integrated luminosity of 5.4 fb⁻¹. The B_s⁰ mesons are reconstructed via the decays B_s⁰→J/ψϕ and B_s⁰→D_s⁻π⁺ . The ratio of branching fractions is measured to be B(B_c⁺→B_s⁰π⁺)/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.
