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

The measurements of the prompt and non-prompt differential cross-sections of $J/\psi$ and $\psi(2\mathrm{S})$ mesons with $p_{T}$ between 60 and 360 GeV and rapidity range $|y|<2$ are reported. Furthermore, the measurements of the non-prompt fractions of $\psi(2S)$ and $J/\psi$, and prompt and non-prompt production ratios of $\psi(2S)$ to $J/\psi$ are presented. The analysis is performed using $pp$ collision data recorded by the ATLAS detector at $\sqrt{s}=13$ TeC collected between 2015 and 2018, corresponding to $139$~fb$^{-1}$ of integrated luminosity.
