noimgSignal yield $n_{\rm sig}$, efficiency $\epsilon\,(\%)$, and measured differential cross sections $\dsdpt$ and $\dsdy$, compared to the \MCATNLO and \PYTHIA\ predictions, in different \ptb\ and \yb\ intervals. The uncertainties on the measured cross sections are statistical and systematic, respectively, excluding the common luminosity of $4\%$ and the $1.4\%$ from the $\JPsi$ and $\phi$ branching fractions.
Projections of the fit results in $\MB$ (a) and $ct$ (b) for $8< \ptb <50$~GeV/$c$ and $\yb < 2.4$. The curves in each plot are: the sum of all contributions (solid line); signal (dashed); prompt $\JPsi$ (dotted); and non-prompt $\JPsi$ (dot-dashed). For better visibility of the individual contributions, plot (a) includes the requirement $ct>0.01\ {\rm cm}$.

Measured differential cross sections $\dsdpt$ (a) and $\dsdy$ (b) compared with theoretical predictions. The (yellow) band represents the sum in quadrature of statistical and systematic uncertainties. The dotted (red) line is the \PYTHIA\ prediction; the solid and dashed (blue) lines are the \MCATNLO prediction and its uncertainty, respectively. The common uncertainties of $4\%$ on the data points, due to the integrated luminosity, and of $30\%$ on the theory curves, due to the \psiphi\ branching fraction, are not shown.
