This study explores the system size dependence of two novel features observed at RHIC with heavy ions: the hadron suppression at high-$p_{T}$ and the anomalous baryon to meson enhancement at intermediate transverse momenta. Both phenomena could be attributed to the creation of a new form of QCD matter. The results presented here bridge the system size gap between the available pp and Au+Au data, and allow the detailed exploration for the on-set of the novel features. Comparative analysis of all available 200 GeV data indicates that the system size is a major factor determining both the magnitude of the hadron spectra suppression at large transverse momenta and the relative baryon to meson enhancement.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.98965.v1/t1","@type":"Dataset","description":"Transverse momentum spectra of pions (a) and protons (b) produced in Cu+Cu collisions at $\\sqrt{s_{NN}}$=200 GeV.
