Abstract

Inclusive J/ψ production is studied in minimum-bias proton-proton collisions at a centre-of-mass energy of s = 5.02 TeV by ALICE at the CERN LHC. The measurement is performed at mid-rapidity (|y| < 0.9) in the dielectron decay channel down to zero transverse momentum p<inf>T</inf>, using a data sample corresponding to an integrated luminosity of L<inf>int</inf> = 19.4 ± 0.4 nb<sup>−1</sup>. The measured p<inf>T</inf>-integrated inclusive J/ψ production cross sec- tion is dσ/dy = 5.64 ± 0.22(stat.) ± 0.33(syst.) ± 0.12(lumi.) μb. The p<inf>T</inf>-differential cross section d<sup>2</sup>σ/dp<inf>T</inf>dy is measured in the p<inf>T</inf> range 0–10 GeV/c and compared with state-of- the-art QCD calculations. The J/ψ 〈p<inf>T</inf>〉 and 〈pT2〉 are extracted and compared with results obtained at other collision energies. [Figure not available: see fulltext.].
