Resumo: | The modification of the production of $J/\psi $ , $\psi (2\mathrm {S})$ , and $\varUpsilon (n\mathrm {S})$ ( $n = 1, 2, 3$ ) in p+Pb collisions with respect to their production in pp collisions has been studied. The p+Pb and pp datasets used in this paper correspond to integrated luminosities of $28~\mathrm {nb}^{-1}$ and $25~\mathrm {pb}^{-1}$ respectively, collected in 2013 and 2015 by the ATLAS detector at the LHC, both at a centre-of-mass energy per nucleon pair of 5.02 TeV. The quarkonium states are reconstructed in the dimuon decay channel. The yields of $J/\psi $ and $\psi (\mathrm {2S})$ are separated into prompt and non-prompt sources. The measured quarkonium differential cross sections are presented as a function of rapidity and transverse momentum, as is the nuclear modification factor, $R_{p\mathrm {Pb}}$ for $J/\psi $ and $\varUpsilon (n\mathrm {S})$ . No significant modification of the $J/\psi $ production is observed while $\varUpsilon (n\mathrm {S})$ production is found to be suppressed at low transverse momentum in p+Pb collisions relative to pp collisions. The production of excited charmonium and bottomonium states is found to be suppressed relative to that of the ground states in central p+Pb collisions. |

The modification of the production of $J/\psi $ , $\psi (2\mathrm {S})$ , and $\varUpsilon (n\mathrm {S})$ ( $n = 1, 2, 3$ ) in p+Pb collisions with respect to their production in pp collisions has been studied. The p+Pb and pp datasets used in this paper correspond to integrated luminosities of $28~\mathrm {nb}^{-1}$ and $25~\mathrm {pb}^{-1}$ respectively, collected in 2013 and 2015 by the ATLAS detector at the LHC, both at a centre-of-mass energy per nucleon pair of 5.02 TeV. The quarkonium states are reconstructed in the dimuon decay channel. The yields of $J/\psi $ and $\psi (\mathrm {2S})$ are separated into prompt and non-prompt sources. The measured quarkonium differential cross sections are presented as a function of rapidity and transverse momentum, as is the nuclear modification factor, $R_{p\mathrm {Pb}}$ for $J/\psi $ and $\varUpsilon (n\mathrm {S})$ . No significant modification of the $J/\psi $ production is observed while $\varUpsilon (n\mathrm {S})$ production is found to be suppressed at low transverse momentum in p+Pb collisions relative to pp collisions. The production of excited charmonium and bottomonium states is found to be suppressed relative to that of the ground states in central p+Pb collisions. |
