Popis: International audience; The ratio of branching fractions of $ {B}_c^{+}\to {B}_s^0{\pi}^{+} $ and $ {B}_c^{+}\to J/\psi {\pi}^{+} $ 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}_s^0 $ mesons are reconstructed via the decays $ {B}_s^0\to J/\psi \phi $ and $ {B}_s^0\to {D}_s^{-}{\pi}^{+} $. The ratio of branching fractions is measured to be $ \mathcal{B}\left({B}_c^{+}\to {B}_s^0{\pi}^{+}\right)/\mathcal{B}\left({B}_c^{+}\to J/\psi {\pi}^{+}\right)=91\pm 10\pm 8\pm 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.[graphic not available: see fulltext]
