description: Production of $B_c^+$ mesons in proton-proton collisions at a center-of-mass energy of 8 TeV is studied with data corresponding to an integrated luminosity of $2.0~{\rm fb}^{-1}$ recorded by the LHCb experiment. The ratio of production cross-sections times branching fractions between the $B_c^+\to J/ψπ^+$ and $B^+\to J/ψK^+$ decays is measured as a function of transverse momentum and rapidity in the regions $0 &lt; p_{\rm T} &lt; 20~{\rm GeV}/c$ and $2.0 &lt; y &lt; 4.5$. The ratio in this kinematic range is measured to be $(0.683\pm0.018\pm0.009)\%$, where the first uncertainty is statistical and the second systematic.
