Abstract (english)	We present the first measurement at the LHC of exclusive J/ψ photoproduction off protons, in ultraperipheral proton-lead collisions at √sNN = 5.02 TeV. Events are selected with a dimuon pair produced either in the rapidity interval, in the laboratory frame, 2.5 <y< 4 (p-Pb) or −3.6 <y< −2.6 (Pb-p), and no other particles observed in the ALICE acceptance. The measured cross sections σ(γ + p → J/ψ + p) are 33.2 ± 2.2 (stat) ± 3.2 (syst) ± 0.7 (theor) nb in p-Pb and 284 ± 36 (stat) ± 27 32 (syst) 26 (theor) nb in Pb-p collisions. We measure this process up to about 700 GeV in the γp center of mass, which is a factor of two larger than the highest energy studied at HERA. The data are consistent with a power law dependence of the J/ψ photoproduction cross section in γp energies from about 20 to 700 GeV, or equivalently, from Bjorken x scaling variable between ~2 × 10^−2 and ~2 × 10^−5, thus indicating no significant change in the gluon density behavior of the proton between HERA and LHC energies.
