  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-Lambdabar yield and the baryon transverse momentum flow
observed in this reaction can only be partially described.
