We discuss general properties of the Color Glass Condensate. We show that predictions for particle production in p(d)A and AA collisions derived from these properties are in agreement with data collected at RHIC.

Noting that the number of gluons in the hadron wave function is discrete, and their formation in the chain of small x evolution occurs over discrete rapidity intervals of Dy ' 1/as, we formulate the discrete version of the Balitsky–Kovchegov evolution equation and show that its solution behaves chaotically in the phenomenologically interesting kinematic region.

We discuss the production of charmed mesons and J/Ψ in p(d)A collisions at high energies. We argue that when the saturation scale Qs characterizing the parton density in a nucleus exceeds the quark mass m, the naive perturbation theory breaks down. Consequently, we calculate the process of heavy quark production in both open and hidden channels in the framework of the parton saturation model (color glass condensate). We demonstrate that at RHIC such a description is in agreement with experimental data on charm production.

The number of gluons in the hadron wave function is discrete, and their formation in the chain of small x evolution occurs over discrete rapidity intervals of Δy≃1/αs. We therefore consider the evolution as a discrete quantum process. We show that the discrete version of the mean-field Kovchegov evolution equation gives rise to strong fluctuations in the scattering amplitude, not present in the continuous equation. We find that if the linear evolution is as fast as predicted by the perturbative BFKL dynamics, the scattering amplitude at high energies exhibits a chaotic behavior. As a consequence, the properties of diffraction at …
