Measurement of the production cross-section of $J/\psi$ and $\psi (2$S$)$ mesons in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

Abstract

Measurements of the differential production cross-sections of prompt and non-prompt $J/\psi$ and $\psi (2$S$)$ mesons with transverse momenta between 8 and 360 GeV and rapidity in the range $|y|<2$ are reported. Furthermore, measurements of the non-prompt fractions of $J/\psi$ and $\psi (2$S$)$, and the prompt and non-prompt $\psi (2$S$)$-to-$J/\psi$ production ratios, are presented. The analysis is performed using 140 fb${}^{-1}$ of $\sqrt{s}=13$ TeV $pp$ collision data recorded by the ATLAS detector at the LHC during the years 2015-2018.
