RECENT PROGRESS IN COMPUTING INITIAL CONDITIONS FOR HIGH ENERGY HEAVY ION COLLISIONS

摘要

Classical methods are used to compute multi-particle production in the initial instants of a high energy heavy ion collision. Non-perturbative expressions are derived relating the distributions of produced partons to those of wee partons in the wavefunctions of the colliding nuclei. The time evolution of components of the stress-energy tensor and the impact parameter dependence of elliptic flow is studied. We discuss the space-time picture that emerges and interpret the RHIC data within this framework.
