Preliminary PHENIX data on Au + Au reactions at s = 130 AGeV suggest that p¯ yields may exceed p- at high pT > 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 non-perturbative component of baryon dynamics. We suggest that baryon junctions provide a possible explanation of the anomalous component. We predict that the p¯ = p- anomaly is limited to a finite pT window and decreases with increasing impact parameter.
