Baryon number transport via gluonic junctions

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 Λ–Λ̄ yield and the baryon transverse momentum flow observed in this reaction can only be partially described.
