Figure Caption

Measured coherent differential cross section of J/psi photoproduction in ultra-peripheral Pb–Pb collisions at √ sNN = 5.02 TeV. The error bars represent the statistical uncertainties, the boxes around the points the systematic uncertainties. The theoretical calculations are also shown. The green band represents the uncertainties of the EPS09 LO calculation.
