> Title: "Identified high-pT spectra in Cu+Cu collisions at $ 
> \sqrt{s_{NN}}$ = 200 GeV"
>
> Abstract: "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-pT 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."
