Prompt and non-prompt J/ψ and ψ(2S) suppression at high transverse momentum in 5.02TeV Pb+Pb collisions with the ATLAS experiment

et al.
Abstract

A measurement of J/ψ$$J/\psi $$ and ψ(2S)$$\psi (2\mathrm {S})$$ production is presented. It is based on a data sample from Pb+Pb collisions at sNN=5.02TeV$$\sqrt{s_{\mathrm {NN}}} = 5.02~\mathrm {TeV}$$ and pp collisions at s=5.02TeV$$\sqrt{s} = 5.02~\mathrm {TeV}$$ recorded by the ATLAS detector at the LHC in 2015, corresponding to an integrated luminosity of 0.42nb-1$$0.42~\mathrm {nb}^{-1}$$ and 25pb-1$$25~\mathrm {pb}^{-1}$$ in Pb+Pb and pp, respectively. The measurements of per-event yields, nuclear modification factors, and non-prompt fractions are performed in the dimuon decay channel for 9
