摘要：

In the framework of k(t)-factorization approach, we consider the production of J/Psi pairs at the LHC conditions. We give predictions on the differential cross sections and discuss the source and the size of theoretical uncertainties. We also present a comparison with collinear parton model showing a dramatic difference in the J/Psi transverse momentum spectrum and J/Psi - J/Psi azimuthal correlations. Finally, we give predictions on the polarization observables in the helicity and Collins-Soper systems.
