| Abstract: | Identified charged kaon, pion and proton spectra and ratios from \sqrt{\rm s_{{NN}}} = 200 and 62.4 GeV Cu+Cu collisions are studied with a hydro-motivated blast-wave and a statistical model framework in order to explore the strangeness production at RHIC and characterize the bulk freeze-out properties of the created system. The spectra are measured at mid-rapidity (|y| < 0.1) over the transverse momentum range of 0.25 < pT < 1.2 GeV/c with particle identification derived from the ionization energy loss in the STAR time projection chamber. The multi-dimensional systematic study of p±, K±, p and \bar{p} production in Cu+Cu, Au+Au, d+Au and p+p collisions is used to discuss the energy, system size and inferred energy density dependence of freeze-out parameters and strangeness production. The new data from Cu+Cu collisions bridge the gap between the smaller d+Au and larger Au+Au systems, allowing a detailed study of the onset of strangeness equilibration at RHIC.
