14:00 → 14:50 Energy dependence of exclusive photoproduction of J/Psi on a proton and a nucleus

Recent data by both ALICE and CMS collaborations on photonuclear J/Psi production seem to indicate that the energy dependence of the total J/Psi photoproduction cross-section requires non-linear QCD evolution equations, such as the BK equation. In this talk we take the following approach to this problem: if non-linear QCD dynamics is present for a lead nucleus, but absent for a proton, the energy dependence of the latter should be well described by NLO BFKL evolution, while for the former this description should fail. Using the GBW model to create the initial condition in both cases, we show preliminary result on such an attempt.

Speakers: Dr Martin Hentschinski (Universidad de las Americas Puebla), Martin Hentschinski (Brookhaven National Laboratory)
