String Junction Effects for Forward and Central Baryon Production in Hadron-Nucleus Collisions
F. W. Bopp, Yu. M. Shabelski
Abstract
The process of baryon number transfer due to string junction propagation in rapidity space is considered. It leads to a significant effect in the net baryon production in pA collisions at mid-rapidities and an even more significant effect in the forward hemisphere for the cases of πA interactions. The results of numerical calculations in the framework of the Quark-Gluon String Model are in reasonable agreement with the data. Special consideration is given to Λproduced in π--A collisions extracted from data of WA89 Collaboration.
