The role of jet quenching in the p-bar >= pi- anomaly at RHIC

Original · EN

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