Abstract
A new version, v2.0, of the HIJING/BB Monte Carlo nuclear collision event generator is introduced in order to explore further the possible role of baryon junctions loops in the baryon/meson anomaly (2 < pT < 5 GeV/c) observed in 200A GeV Au+Au reactions at RHIC. We show that junction loops with an enhanced intrinsic kT≈ 1 GeV/c transverse momentum kick may provide a partial explanation of the anomaly as well as other important baryon stopping observables.
