Central-to-peripheral nuclear modification factors in Pb-Pb collisions at $\sqrt{s_{NN}}$= 17.3 GeV

We present central-to-peripheral nuclear modification factors, $R_{CP}$, for the $p_{T}$ distributions of $K_{S}^{0}$, $\Lambda$, $\bar{\Lambda}$, 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...

description We present central-to-peripheral nuclear modification factors, $R_{CP}$, for the $p_{T}$ distributions of $K_{S}^{0}$, $\Lambda$, $\bar{\Lambda}$, 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 $\Lambda$ $R_{CP}$ $p_{T}$ are similar in shape to those measured at $\sqrt{s_{NN}}$ = 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 $p_{T}$ $\approx$ 3-4 GeV/$c$, unless sizeable parton energy loss is included in the calculation.
