Sažetak
We report new results on identified (anti)proton and charged pion spectra at large transverse momenta (3<$p_{; ; ; T}; ; ; $<10 GeV/c) from Cu+Cu collisions at $\sqrt{; ; ; s_{; ; ; NN}; ; ; }; ; ; $=200 GeV using the STAR detector at the Relativistic Heavy Ion Collider (RHIC). This study explores the system size dependence of two novel features observed at RHIC with heavy ions: the hadron suppression at high-$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.
