Identified Particle Distributions inppandAu+AuCollisions atsNN=200GeV

Transverse mass and rapidity distributions for charged pions, charged kaons, protons, and antiprotons are reported for $\sqrt{s_{NN}}=200\mathrm{GeV}$ $pp$ and $\mathrm{Au}+\mathrm{Au}$ collisions at Relativistic Heary Ion Collider (RHIC). Chemical and kinetic equilibrium model fits to our data reveal strong radial flow and long duration from chemical to kinetic freeze-out in central $\mathrm{Au}+\mathrm{Au}$ collisions. The chemical freeze-out temperature appears to be independent of initial conditions at RHIC energies.
