Description

Transverse momentum spectra of charged pions, protons, antiprotons, charged kaons, K⁰_s and Lambdas at midrapidity were measured at high p_T in Pb+Pb collisions at 17.3 GeV/nucleon cms energy by the CERN-NA49 experiment. We use these results to outline an energy dependence picture of the phenomena, discovered at RHIC energies: the energy dependence of high p_T particle suppression, and of baryon production relative to meson production. Results are also compared to pQCD calculations. Our results show that, in the context of jet-quenching models, suppression of high-p_T particles may be already present at SPS energies. Apart from this observation, also other puzzling features of the particle spectra will be pointed out.
