Baryon Junction Stopping at the SPS and RHIC via HIJING/B

Baryon stopping at the SPS and RHIC energies is calculated by introducing a new baryon junction mechanism into HIJING. The exchange of a baryon junction, according to Regge phenomenology, leads to a cosh(y/2) rapidity dependence and an s^(-1/4) energy dependence of the inclusive baryon cross section. This baryon junction dynamics also leads naturally to enhanced p_T broadening in pA and AA together with enhanced mid-rapidity hyperon production.
