Query: Dynamic Characteristics of Proton-Proton Collisions   The fact that quark-quark, quark-gluon and gluon-gluon interactions are
different sources of particle production in proton-proton collision at high
energy is investigated in this work. The variation of the multiplicity and
pseudo-rapidity distributions of the created particles with the interaction
energy is studied. The limits at which Feynman and KNO scaling are violated and
their relations with the mechanism of the production sources are considered in
view of some theoretical aspects.
