Central-to-peripheral nuclear modification factors in Pb-Pb collisions at sqrtsNN = 17.3 GeV
Abstract
We present central-to-peripheral nuclear modification factors, RCP, for the pT distributions of K0S, Lambda, Anti-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 K0S and Lambda RCP(pT) are similar in shape to those measured at sqrtsNN = 200 GeV at RHIC, though they are larger in absolute value. We have compared our K0S 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.
