| Abstract: | We present central-to-peripheral nuclear modification factors, RCP, for the pT distributions of , Λ, , and negatively charged particles, measured at central rapidity in Pb–Pb collisions at top SPS energy. The data cover the 55% most central fraction of the inelastic cross section. The and Λ RCP(pT) are similar in shape to those measured at at RHIC, though they are larger in absolute value. We have compared our RCP data to a theoretical calculation. The prediction overestimates the data at pT≈3–4 GeV/c, unless sizeable parton energy loss is included in the calculation. |
