Abstract
The exclusive photoproduction of upsilon state ϒð1SÞ and its radially excited states ϒð2S; 3SÞ is investigated in the context of ultraperipheral collisions at the LHC energies. Predictions are presented for their production in proton-proton, proton-nucleus, and nucleus-nucleus collision at the energies available at the LHC Run 2. The rapidity and transverse-momentum distributions are shown, and the robustness of the model is tested against the experimental results considering ψð1S; 2SÞ and ϒð1S ...
The exclusive photoproduction of upsilon state ϒð1SÞ and its radially excited states ϒð2S; 3SÞ is investigated in the context of ultraperipheral collisions at the LHC energies. Predictions are presented for their production in proton-proton, proton-nucleus, and nucleus-nucleus collision at the energies available at the LHC Run 2. The rapidity and transverse-momentum distributions are shown, and the robustness of the model is tested against the experimental results considering ψð1S; 2SÞ and ϒð1SÞ states. The theoretical framework considered in the analysis is the light-cone color dipole formalism, which includes consistently parton saturation effects and nuclear shadowing corrections. ...
