Abstract

Using the general notion of cross section fluctuations in hadron-nucleus scattering at high energies, we derive an expression for the cross section of incoherent J/ψ photoproduction on heavy nuclei dσγAJ/ψY/dt, which includes both elastic dσγpJ/ψp/dt and proton-dissociation dσγpJ/ψY/dt photoproduction on target nucleons. We find that, with good accuracy, dσγAJ/ψY/dt can be expressed as a product of the sum of the dσγpJ/ψp/dt and dσγpJ/ψY/dt cross sections, which have been measured at HERA, and the common nuclear shadowing factor, which is calculated using the leading twist nuclear shadowing model. Our prediction for the cross section of incoherent J/ψ photoproduction in Pb-Pb ultraperipheral collisions at sNN=2.76TeV and y=0,dσAAJ/ψAY(y=0)/dy=0.591.24mb agrees within significant theoretical uncertainties with the data of the ALICE Collaboration.
