  A significant asymmetry in baryon/antibaryon yields in the central region of
high energy collisions is observed when the initial state has non-zero baryon
charge. This asymmetry is connected with the possibility of a baryon charge
diffusion in rapidity space. Evidently, such a diffusion should decrease the
baryon charge in the fragmentation region leading to the corresponding decrease
of the multiplicity of leading baryons. As a result, a new mechanism for
Feynman scaling violation in the fragmentation region is obtained. We present
the quantitative predictions for the Feynman scaling violation at LHC energies
and even at highier energies that can be important for cosmic ray physics.
