Abstract
The inclusion of string fusion in Dual Parton Model results in the app earance of diquark-antidiquark pairs in the sea with comparatively lar ge Feynman-x. Such antidiquarks can fragment into fast antibaryons, th us increasing several times the corresponding yields in high energy pp collisions for x(F) similar to 0.8 divided by 0.9. String fusion also results in an unusual dependence of inclusive spectra on the multipli city of secondaries. Some numerical estimations are presented.
