Identified hadron spectra from pp, dA and AA collisions

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.
