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<p_T<5\phantom\rule0.3em0exGeV∕c) observed in 200A\phantom\rule0.3em0exGeV Au+Au reactions at RHIC. We show that junction loops with an enhanced intrinsic k_T\ensuremath≈1\phantom\rule0.3em0exGeV∕c transverse momentum kick may provide a partial explanation of the anomaly as well as other important baryon stopping observables.
