| 英文摘要 | The modification of the production of j/psi, psi(2s), and gamma (ns) (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 nb(-1) and 25 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(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-ppb for j/psi and psi (ns). no significant modification of the j/psi production is observed while gamma (ns) 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. |
