Measurement of the differential cross-sections of prompt and non-prompt production of $J\mathrm{/}\psi$ and $\psi (2\mathrm{S})$ in $pp$ collisions at $\sqrt{s}=7$ and $8$ TeV with the ATLAS detector

The production rates of prompt and non-prompt $J\mathrm{/}\psi$ and $\psi (2\mathrm{S})$ mesons are measured using 2.1 $f{b}^{-1}$ and 11.4 $f{b}^{-1}$ of data collected with the ATLAS experiment at the LHC, in proton-proton collisions at $\sqrt{s}=7$ and 8 TeV respectively. Production cross-sections for both prompt and non-prompt production sources, ratios of $\psi (2\mathrm{S})$ to $J\mathrm{/}\psi$ production, and fractions of non-prompt to inclusive production for $J\mathrm{/}\psi$ and $\psi (2\mathrm{S})$ are measured double-differentially as a function of meson $p_T$ and rapidity. These measurements are made in a restricted fiducial volume and also corrected for geometrical acceptance after which they are compared to a variety of theoretical predictions.
