Production cross-sections for both prompt and non-prompt production sources, ratios of ψ(2S) to J/ψ production, and fractions of non-prompt to inclusive production for J/ψ and ψ(2S) are measured double-differentially as a function of meson pT 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.en-USJournal Article2017-07-2010.1140/epjc/s10052-016-4050-8
