Hard and soft QCD in charmonium production
C. B. Mariotto, M. B. Gay Ducati, G. Ingelman
We show that both hard perturbative and soft non-perturbative QCD effects are important in hadroproduction of charmonium. Observed and distributions of J/psi in fix…

The Asymptotic Regime of High Density QCD
M. B. Gay Ducati, V. P. Gonçalves
We discuss the distinct approaches for high density QCD (hdQCD) in the asymptotic regime of large values of parton density. We derive the AGL equation for running coupling constant…
