Measurements of the differential production cross-sections of prompt and non-prompt J/psi and psi(2S) 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(2S), and the prompt and non-prompt psi(2S)-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.

Abstract
Measurements of the differential production cross-sections of prompt and non-prompt J/psi and psi(2S) 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(2S), and the prompt and non-prompt psi(2S)-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.File in questo prodotto:
