J/$\psi$ photoproduction in ultra-peripheral PbPb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV with CMS

In ultra-peripheral heavy-ion collisions, photon-induced interactions between collid- ing nuclei occur at large impact parameters. In this thesis, a study of J/ y photopro- duction in ultra-peripheral PbPb collisions at p s NN = 2 : 76 TeV is presented. This was carried out using data collected by the Compact Muon Solenoid in 2011. An inte- grated luminosity of 143 m b
