Identified Hadron Spectra From pp, dA and AA collisions
J. Velkovska
Abstract
The experimental data for identified hadron spectra from pp,d+A and AA collisions are reviewed. Three regions with different dominant production mechanisms are considered: soft region (pt <2 GeV/c) - with large degree of collectivity and thermalization, hard particle production which exhibits jet-quenching in Au+Au collisions at RHIC and intermediate region (2 < pt <5 GeV/c) with distinct baryon dynamics. Cronin effect, nuclear modification factors and jet-like correlations are studied with the goal of understanding the baryon dynamics at RHIC.
