Abstract:
The ratio of branching fractions of $$ {B}_c^{+}\to {B}_s^0{\pi}^{+} $$ B c + → B s 0 π + and $$ {B}_c^{+}\to J/\psi {\pi}^{+} $$ B c + → J / ψ π + 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 $$ {B}_s^0 $$ B s 0 mesons are reconstructed via the decays $$ {B}_s^0\to J/\psi \phi $$ B s 0 → J / ψϕ and $$ {B}_s^0\to {D}_s^{-}{\pi}^{+} $$ B s 0 → D s − π + . The ratio of branching fractions is measured to be $$ \mathcal{B}\left({B}_c^{+}\to {B}_s^0{\pi}^{+}\right)/\mathcal{B}\left({B}_c^{+}\to J/\psi {\pi}^{+}\right)=91\pm 10\pm 8\pm 3 $$ B B c + → B s 0 π + / B B c + → J / ψ π + = 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.
