The Regge-Mueller formalism is used to describe the inclusive spectrum of the
proton in pp collisions. From such a description the energy dependences of
both average inelasticity and leading proton multiplicity are calculated. These
quantities are then used to establish the connection between the average
charged particle multiplicities measured in {\bf e+e−} and {\bf pp/pˉp} processes. The description obtained for the leading proton cross section
implies that Feynman scaling is strongly violated only at the extreme values of
xF, that is at the central region (xF≈0) and at the diffraction
region (xF≈1), while it is approximately observed in the
intermediate region of the spectrum.Comment: 20 pages, 10 figures, to be published in Physical Review
