Abstract:

√s=[NN]39.0 and 62.4 GeV have been presented. Comparison of nuclear modification factors measured for π0-mesons in Cu+Cu and Au+Au collisions at √s[NN]= 22.4, 39.0, 62.4 and 200 GeV was carried out. It is shown that maximum energy of SPS synchrotron at CERN is not enough to reveal the jet-quenching effect.
