dc.description.abstractThe ALICE Collaboration has measured the energy dependence of exclusive photoproduction of J/ψJ/ψ vector mesons off proton targets in ultra–peripheral p–Pb collisions at a centre-of-mass energy per nucleon pair sNN−−−√=5.02sNN=5.02 TeV. The e++e−− and μ+μ−μ+μ− decay channels are used to measure the cross section as a function of the rapidity of the J/ψJ/ψ in the range −2.5&lt;y&lt;2.7−2.5&lt;y&lt;2.7, corresponding to an energy in the γγp centre-of-mass in the interval 40&lt;Wγp&lt;55040&lt;Wγp&lt;550 GeV. The measurements, which are consistent with a power law dependence of the exclusive J/ψ photoproduction cross section, are compared to previous results from HERA and the LHC and to several theoretical models. They are found to be compatible with previous measurements.
