N2 - We present central-to-peripheral nuclear modification factors, R CP, for the pT distributions of KS0, Λ, 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 KS0 and Λ RCP(pT) are similar in shape to those measured at √sNN = 200 GeV at RHIC, though they are larger in absolute value. We have compared our KS0 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.
