Abstract

Recent results from the proton-proton collision data taken by the ATLAS experiment on the charmonium production and on the Bc+ meson production and decays are presented. The measurement of J/ψ meson and ψ(2S) meson differential cross sections is reported. New results on the Bc+ meson decays to J/ψ Ds(*)  final states are included. Both studies are based on pp collision data collected at √s=13  TeV during the LHC Run 2, corresponding to an integrated luminosity of 139 fb-1.  The measurement of the differential ratios of the Bc+and B+ mesons production cross sections at √s=8 TeV with an integrated luminosity of 20.3 fb-1is also discussed.
