| Özet |
| 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, X n 0 n, is measured with the CMS experiment in ultra-peripheral PbPb collisions at s N N= 2.76 TeV. The analysis is based on a data sample corresponding to an integrated luminosity of 159 μb− 1, collected during the 2011 PbPb run. The J/ψ mesons are reconstructed in the dimuon decay channel, while neutrons are detected using zero degree calorimeters. The measured cross section is d σ X n 0 n coh/d y (J/ψ)= 0.36±0.04 (stat)±0.04 (syst) mb in the rapidity interval 1.8<| y|< 2.3. Using a model for the relative rate of coherent photoproduction processes, this X n 0 n measurement gives a total coherent photoproduction cross section of d σ coh/d y (J/ψ)= 1.82±0.22 (stat)±0.20 (syst)±0.19 (theo) mb. The data strongly disfavor the impulse approximation … |
