Photoproduction of the coherent $J/\psi$ accompanied by the forward neutron emission in ultra-peripheral PbPb collisions at 2.76~TeV
The cross section of coherent $J/\psi$ photoproduction accompanied by forward neutrons is measured in ultra-peripheral PbPb collisions at $\sqrt{s_{NN}} = 2.76$ TeV with the CMS experiment at the LHC. $J/\psi$ mesons are reconstructed by their decay into muon pairs while the neutrons are measured by...
