Energy dependence of dissociative $J/\psi$ photoproduction as a signature of gluon saturation at the LHC

J. Cepila, J. G. Contreras, J. D. Tapia Takaki

We have developed a model in which the quantum fluctuations of the proton structure are characterised by hot spots, whose number grows with decreasing Bjorken-$x$. Our model reprod…
