摘要：

PHENIX data on Au+Au at roots=130A GeV suggest that (p) over bar yields may exceed pi(-) at high p(T)>2 GeV/c. We propose that jet quenching in central collisions suppresses the hard PQCD component of the spectra in central A+A reactions, thereby exposing a novel component of baryon dynamics that we attribute to (gluonic) bayron junctions. We predict that the observed (p) over bar greater than or similar topi(-) and the p>pi(+) anomaly at p(T)similar to2 GeV/c is limited to a finite p(T) window that decreases with increasing impact parameter.
