Coherent J/ψ photoproduction at midrapidity in Pb−Pb collisions at √sNN = 5.02 TeV
The coherent J/ ψ photoproduction cross section is measured for the first time at midrapidity in peripheral to semicentral Pb−Pb collisions at sNN=5.02 TeV. The centrality differential cross section d σ /d y is reported for the centrality range 40–90%, together with the doubly-differential cross section d2 σ /d y d p T, extracted in two peripheral centrality classes. The J/ ψ mesons are reconstruc
