摘要：

A novel non-perturbative gluon junction mechanism is introduced within the HIJING/B nuclear collision event generator to calculate baryon number transport and hyperon production in pA and AA collisions. This gluonic mechanism can account for the observed large mid-rapidity valence baryon yield in Pb + Pb at 160 AGeV and predicts high initial baryon densities at RHIC. However, the highly enhanced Lambda - <(Lambda)over bar> yield and the baryon transverse momentum flow observed in this reaction can only be partially described.
