The double vector meson production in two-photon collisions is addressed assuming that the color singlet t-channel exchange carries large momentum transfer. We consider the non-forward solution of the BFKL equation at high energy and large momentum t

The contribution of the QCD pomeron to the process AA → AAJ/Ψ J/Ψ is discussed. We focus on the photon–photon collision, with the quasi-real photon coming from theWeizs¨acker–Williams spectrum of the nuclei. We calculate the cross section fo

The double-meson production in ultraperipheral heavy-ions collisions is addressed, focusing on the particular case of ρJ/Ψ from two-photon reactions. The cross section at photon level is obtained using distinct parameterizations for the gluon distr

We investigate heavy quark photoproduction based on the k'-factorization approach, focusing on the results from the saturation model. The deviations between the results using the unintegrated gluon distribution considering the saturation model and th

Our goal is the study of color effects on the J/[Psi] mesons production, as well as the study of their elastic production. We use the color evaporation model CEM, where a single factor takes into account the probability that the cc produced in a colo
