    abstract = "We present central-to-peripheral nuclear modification factors, R-CP, for
the (PT) distributions of K-S(0), Lambda, Lambda, 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 K-S(0) and Lambda R-CP((PT)) are similar in shape to
those measured at root sNN = 200 GeV at RHIC, though they are larger in
absolute value. We have compared our K-S(0) R-CP data to a theoretical
calculation. The prediction overestimates the data at (PT) approximate
to 3-4 GeV/c, unless sizeable parton energy loss is included in the
calculation. (c) 2005 Elsevier B.V. All rights reserved."
