The measurement is performed with the ALICE detector via the dimuon decay channel at forward rapidity ($2.5<y<4$). The nuclear modification factor at very low $p_{\\rm T}$ and the coherent photoproduction cross section are measured as a function of centrality down to the 10% most central collisions. These results extend the previous study at $\\sqrt{s_{\\rm NN}} = 2.76$ TeV, confirming the clear excess over hadronic production in the $p_{\\rm T}$ range 0$-$0.3 GeV/$c$ and the centrality range 70$-$90%, and establishing an excess with a significance greater than 5$\\sigma$ also in the 50$-$70% and 30$-$50% centrality ranges. The results are compared with earlier measurements at $\\sqrt{s_{\\rm NN}} = 2.76$ TeV and with different theoretical predictions aiming at describing how coherent photoproduction occurs in hadronic interactions with nuclear overlap.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.134024.v1/t1","@type":"Dataset","description":"J/$\\psi$ nuclear modification factor as a function of $\\langle N_{\\rm part}\\rangle$ measured in the rapidity range 2.5 &lt; y &lt;...","name":"Figure 1a"},{"@id":"https://doi.org/10.17182/hepdata.134024.v1/t2","@type":"Dataset","description":"J/$\\psi$ nuclear modification factor as a function of $\\langle N_{\\rm part} \\rangle$ measured in the rapidity range 2.5 &lt; y...","name":"Figure 1b"},{"@id":"https://doi.org/10.17182/hepdata.134024.v1/t3","@type":"Dataset","description":"J/$\\psi$ nuclear modification factor as a function of $\\langle N_{\\rm part} \\rangle$ measured in the rapidity range 2.5 &lt; y...","name":"Figure 1c"},{"@id":"https://doi.org/10.17182/hepdata.134024.v1/t4","@type":"Dataset","description":"J/$\\psi$ coherent photoproduction cross section as a function of $\\langle N_{\\rm part}\\rangle$ at forward rapidity in Pb\u2013Pb collisions at $\\sqrt{s_{\\rm...","name":"Figure 2"},{"@id":"https://doi.org/10.17182/hepdata.134024.v1/t5","@type":"Dataset","description":"J/$\\psi$ coherent photoproduction cross section ratio for two different energies ($\\sqrt{s_{\\rm NN}}$ = 5.02 TeV over $\\sqrt{s_{\\rm NN}}$ = 2.76...","name":"Figure 3"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2071183?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/134024"}],"inLanguage":"en","name":"Photoproduction of low-$p_{\\rm T}$ J/$\\psi$ from peripheral to central Pb$-$Pb collisions at 5.02 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2071183?version=1","version":1}
