Abstract (data abstract)
CERN-LHC. The production rates of prompt and non-prompt J/ψ and ψ(2S) mesons are measured using 140 fb1 of data collected with the ATLAS experiment at the LHC, in proton-proton collisions at s=13 TeV. 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.

Version 2 modifications: Fixed tables 3 and 4 which by mistake included a few bins above 140 GeV where measurements were not performed for psi(2S).
