 Title: Measurement of quarkonium production in proton–lead and proton–proton collisions at 5.02TeV with the ATLAS detector Authors: The ATLAS CollaborationSultansoy, Saleh Keywords: Collisionsproductionmatter effects Issue Date: Mar-2018 Publisher: Springer New York LLC Source: ATLAS collaboration. (2018). Measurement of quarkonium production in proton–lead and proton–proton collisions at 5.02~\mathrm {TeV}  with the ATLAS detector. The European Physical Journal C, 78(3), 171. Abstract: The modification of the production of J/ ?, ?(2 S) , and ?(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 28nb-1 and 25pb-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/ ? and ?(2 S) 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, Rp Pb for J/ ? and ?(nS). No significant modification of the J/ ? production is observed while ?(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. © 2018, CERN for the benefit of the ATLAS collaboration.
