The centrality differential cross section ${\\rm d} \u03c3/ {\\rm d}y$ is reported for the centrality range 40-90%, together with the doubly-differential cross section ${\\rm d}^2 \u03c3/{\\rm d}y {\\rm d} p_{\\rm T}$, extracted in two peripheral centrality classes. The J/$\u03c8$ mesons are reconstructed in the dielectron channel, in the rapidity interval $|y| < 0.9$ using the ALICE central barrel detectors. The J/$\u03c8$ cross section at midrapidity is statistically compatible to the earlier ALICE measurement at forward rapidity and at the same centre-of-mass energy, and shows only a mild centrality dependence over the covered range. Several sets of theoretical calculations taking into account the hadronic overlap in the collisions but ignoring possible final-state effects from a hot expanding medium are found to give a fairly good description of the current measurements within uncertainties.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.166012.v1/t1","@type":"Dataset","description":"Coherent J/$\\psi$ cross section as a function of the number of participant nucleons at midrapidity in Pb-Pb collisions at $\\sqrt(s_{NN})$...","name":"Fig2a"},{"@id":"https://doi.org/10.17182/hepdata.166012.v1/t2","@type":"Dataset","description":"Ratio of coherent J/$\\psi$ cross section between peripheral and ultra peripheral collisions as a function of the number of participant...","name":"Fig2b"},{"@id":"https://doi.org/10.17182/hepdata.166012.v1/t3","@type":"Dataset","description":"Coherent J/$\\psi$ cross section as a function of $p_T$ at midrapidity in 50-70% Pb-Pb collisions at $\\sqrt(s_{NN})$ = 5.02 TeV....","name":"Fig3a"},{"@id":"https://doi.org/10.17182/hepdata.166012.v1/t4","@type":"Dataset","description":"Coherent J/$\\psi$ cross section as a function of $p_T$ at midrapidity in 70-90% Pb-Pb collisions at $\\sqrt(s_{NN})$ = 5.02 TeV....","name":"Fig3b"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2829848?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/166012"}],"inLanguage":"en","name":"Coherent J/$\\psi$ photoproduction at midrapidity in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2829848?version=1","version":1}
