Using the general framework of quantum field kinetics we consider new principles to compute initial distribution of quarks and gluons after the first hard interaction of heavy ions. We start by rewriting the integral equations of QCD in a form which is a generalization of the familiar QCD evolution equations. These equations describe both space-time and (x,Q2) evolution before the collision and allow one to use the ep DIS data without reference to parton phenomenology. A new technique generates perturbation theory that avoids double counting of the processes, does not contain an artificial factorization scale, and does not require low-momentum cut-offs since infrared behavior is controlled by the DIS data.
