Abstract
The process of baryon number transfer due to string junction
propagation
in rapidity space is analyzed. It has a significant effect
on the net baryon production in
pp collisions at mid-rapidities
and
an even larger effect in the forward hemisphere in the cases
of
and
interactions. The results of numerical
calculations in the framework of the quark-gluon string model
are in
reasonable agreement with the data.
