Resumo: The exclusive photoproduction of ϒðnSÞ states was calculated in ultraperipheral collisions for coherent and incoherent process in PbPb at sNN p ¼ 5.5 TeV. Different dipole models were compared in the theoretical framework of light-cone color dipole formalism. Moreover, we calculated the differential cross section for the Upsilon states and their total cross section for two intervals of rapidity: jyj ≤ 4 4 and 2 ≤ y ≤ 4.5. A systematic study is done on the theoretical uncertainties associated to the production, and predictions are presented for the first time for the incoherent cross section of the radially excited states.
