Photoproduction of Upsilon states in ultraperipheral collisions at the CERN Large Hadron Collider within the color dipole approach

Abstract

The exclusive photoproduction of upsilon states ${\rm Y}(1S)$ and its radially excited states ${\rm Y}(2S,3S)$ is investigated in the context of ultra-peripheral 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 $\psi (1S,2S)$ and ${\rm Y}(1S)$ 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.
