Baryon Number Transfer in High Energy $hp$ Collisions
  The process of baryon number transfer due to string junction propagation in rapidity is considered. It has a significant effect in the net baryon production in $pp$ collisions at mid-rapidities and an even larger effect in the forward hemisphere in the cases of $\pi p$ and $\gamma p$ interactions. The results of numerical calculations in the framework of the Quark-Gluon String Model are in reasonable agreement with the data with the same parameter values for different energies.
