dc.description.abstract | This paper reports the measurement of J/ψ meson production in proton–proton (pp) and proton–lead (pPb) collisions at a center-of-mass energy per nucleon pair of 5.02TeV by the CMS experiment at the LHC. The data samples used in the analysis correspond to integrated luminosities of 28pb−1 and 35nb−1 for pp and pPb collisions, respectively. Prompt and nonprompt J/ψ mesons, the latter produced in the decay of B hadrons, are measured in their dimuon decay channels. Differential cross sections are measured in the transverse momentum range of 2<pT<30GeV/c, and center-of-mass rapidity ranges of |yCM|<2.4 (pp) and −2.87<yCM<1.93 (pPb). The nuclear modification factor, RpPb, is measured as a function of both pT and yCM. Small modifications to the J/ψ cross sections are observed in pPb relative to pp collisions. The ratio of J/ψ production cross sections in p-going and Pb-going directions, RFB, studied as functions of pT and yCM, shows a significant decrease for increasing transverse energy deposited at large pseudorapidities. These results, which cover a wide kinematic range, provide new insight on the role of cold nuclear matter effects on prompt and nonprompt J/ψ production. | en_US |
