Midrapidity inclusive densities in high energy pp collisions in additive quark model

High energy (CERN SPS and LHC) inelastic pp (pp¯[12pt]{minimal} {amsmath} {wasysym} {amsfonts} {amssymb} {amsbsy} {mathrsfs} {upgreek} {}{-69pt} {document}pp̄{document}) scattering is treated in the framework of the additive quark model together with Pomeron exchange theory. We extract the midrapidity inclusive density of the charged secondaries produced in a single quark–quark collision and investigate its energy dependence. Predictions for the πp[12pt]{minimal} {amsmath} {wasysym} {amsfonts} {amssymb} {amsbsy} {mathrsfs} {upgreek} {}{-69pt} {document}π p{document} collisions are presented.
