Latest results of the PHENIX, PHOBOS, BRAHMS & STAR Collaborations
from 200-GeV per nucleon gold-gold and deuteron-gold nuclear
collisions. In the Au-Au data, high-transverse-momentum particles are
suppressed (red data in PHOBOS & BRAHMS) and there is only one peak in
the pair-correlation plot (STAR); both results are as expected if a
quark-gluon plasma forms. A QGP is not expected in d-Au collisions
and this data show no high-pT suppression (PHENIX) and two peaks.
