Phenomenological description of the parton-parton interaction in high-transverse-momentum collisions. [Total cross sections]

· Phys. Rev., D; (United States)
A phenomenological quark-quark scattering model is presented which reproduces the inclusive high-transverse-momentum data from CERN ISR and Fermilab for the processes pp ..-->.. cX and pn ..-->.. cX, where c = ..pi../sup plus-or-minus/,..pi../sup 0/,K/sup plus-or-minus/,p,p-bar. This model is obtained by multiplying the usual parton-parton scattering amplitude by the factor (1 - t/B)/sup -2/ where -t is the square of the gluon 4-momentum and B = 18 GeV/sup 2/. The single parameter B describes both the x/sub perpendicular/ dependence at constant s and the s (or p/sub perpendicular/) dependence at constant x/sub perpendicular/ for all c at all energies. An additional normalization constant is needed for each particle to fix the overall scale of the total cross section.
