The data have been recorded by the CERES experiment at the CERN-SPS. The correlations are Studied as function of transverse momentum, particle charge and collision centrality. We observe a jet-like structure in the vicinity of a high-pi trigger particle and a broad back-to-back distribution. The yields of associated particles per trigger show a strong dependence on the trigger/associate charge combination. A comparison to PYTHIA confirms the jet-like pattern at the nearside but suggests a strong modification at the away-side, implying significant energy transfer of the hard-scattered parton to the medium.
