The ratio of the production cross sections times branching fractions $\left(\sigma \left({\mathrm{B}}_{\mathrm{c}}^{\pm}\right)\mathrm{\mathcal{B}}\left({\mathrm{B}}_{\mathrm{c}}^{\pm}\to \mathrm{J}/\psi {\pi}^{\pm}\right)\right)/\left(\sigma \left({\mathrm{B}}^{\pm}\right)\mathrm{\mathcal{B}}\left({\mathrm{B}}^{\pm}\to \mathrm{J}/\psi {K}^{\pm}\right)\right)$ is studied in proton-proton collisions at a center-of-mass energy of 7 TeV with the CMS detector at the LHC. The kinematic region investigated requires B$_c^{\pm}$ …
