Abstract
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 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. ...
