Coherent J/ψ photoproduction in ultra-peripheral Pb–Pb collisions with ALICE at the LHC
There are several predictions for the behaviour of the gluon distribution in nuclei at small Bjorken-x and experimental data are needed to choose among them. This is achieved by measuring the cross section of processes specially sensitive to this parton distribution. The high flux of photons from le...
