Abstract:
Transverse momentum spectra of produced hadrons in ultrarelativistic nuclear collisions provide valuable information on particle production mechanisms as well as dynamics and properties of the produced matter. The spectral shape can be used to obtain the transverse radial flow as it is entirely generated during the collision and therefore reflect the collision dynamics and the system temperature at the thermal freeze-out. We will present measurements of identified charged hadron production at diferent collision centralities from Au+Au and p+p collisions at RHIC energies. The mass and centrality dependence of effective temperatures for the particles produced in the collision will be shown and discussed. The results are also compared to previous measurements at various energies. In addition, comparisons with results from simulated heavy ion collisions using the most important simulation codes from this field will be presented.
