We report on the prompt and nonprompt J/ψ meson production from CMS, using 34.6 nb−1 of proton-lead (pPb) data recorded in 2013 at 5.02 TeV. The differential production cross sections are analyzed in the transverse momentum range 2 < pT < 30 GeV/c, and the center-of-mass (CM) rapidity region −2.87 < yCM < 1.93. The ratio of J/ψ yields at forward (proton-going direction) and backward (Pb-going direction) is studied in several ranges of pT, rapidity, and the event-activity regions.
