Coherent J/ψ photoproduction in ultra-peripheral PbPb collisions at √{sNN} = 2.76TeV with the CMS experiment
The cross section for coherent J / ψ photoproduction accompanied by at least one neutron on one side of the interaction point and no neutron activity on the other side, Xn0n, is measured with the CMS experiment in ultra-peripheral PbPb collisions at √{sNN} = 2.76TeV. The analysis is based on a data sample corresponding to an integrated luminosity
