From Classical to Quantum Saturation in the Nuclear Gluon Distribution

الأصل · EN

We study the gluon content of a large nucleus (i) in the semi-classical McLerran-Venugopalan model and (ii) in the high energy limit as given by the quantum evolution of the Color Glass Condensate. We give a simple and qualitative description of the Cronin effect and high-pT suppression in proton-nucleus collisions.
