Coherent and incoherent Upsilon production in ultraperipheral collisions at the Large Hadron Collider

M. B. Gay Ducati, F. Kopp, M. V. T. Machado

The exclusive photoproduction of ${\rm Y}(nS)$ states were calculated in ultra-peripheral collisions for coherent and incoherent process in PbPb at $\sqrt{s_{NN}}$= 5.5 TeV. Different di…
