TL;DR

This paper examines high-energy hadron interactions, emphasizing that multiple parton interactions are negligible and hadron production occurs mainly through three specific string processes, affecting multiplicity distributions.

Contribution

It clarifies the roles of different string processes in hadron production and highlights differences between proton-proton and proton-antiproton interactions at high energies.

Findings

Multiple parton interactions are negligible at high energies.

Hadrons are produced mainly via gluon and quark string processes.

Multiplicity distributions differ between proton-proton and proton-antiproton collisions.

Abstract

Hadrons interaction at high energies is carried out by one color gluon exchange. All quarks and gluons contained in colliding hadrons take part in interaction and production of particles. The contribution of multiple parton interactions is negligible. Multiple hadrons production at high energies occurs only in three types of processes. The first process is hadrons production in gluon string, the second is hadrons production in two quark strings and the third is hadrons production in three quark strings. In proton-proton interaction production of only gluon string and two quark strings is possible. In proton-antiproton interaction production of gluon string, two quark strings and three quark strings is possible. Therefore multiplicity distributions in proton-proton and proton-antiproton interactions are different.
