Invariant-mass distributions of charged B-meson candidates together with the results of the combined fit in the transverse-momentum intervals $10 < p_{\mathrm{T}} < 14~\mathrm{GeV}/c$. The dashed red line shows the parameterized combinatorial background, the blue line represents the Gaussian signal component, and the individual correlated background contributions are shown separately. The solid grey line corresponds to the total fit function, given by the sum of all components.
