Sideward Flow of Charged Particles and Neutrons in Heavy Ion Collisions
To probe the early, high density stage of a heavy-ion collision, it is essential to focus on observables that are minimally distorted during the subsequent processes of expansion, decay of excited states, and chemical freeze-out. It is now widely accepted that correlations characteristic of fluid-like collective behavior (“flow”) fulfill these requirements. Such correlations signal the release of compressional energy, and provide a relative measure of the peak nuclear pressure generated in the collision.
