Magnitude of large-transverse-momentum cross sections

Consistent values for the fundamental dimensional coupling con- stants of hadrons to their valence quarks are determined from large momentum transfer elastic scattering, photoproduction, form factors, and momentum distributions. We then show that the constituent inter- change model hard scattering subprocesses Mq-Mq and Bq-Bq (and their crossing variants) are of sufficient magnitude to account for the i ' normalization as well as the kinematic behavior in pT, angle ,. and s 1 of single particle large transverse momentum inclusive cross sections. -4 The cross-over point where pT scale-invariant qq - qq and gluon terms may dominate the cross section is computed. Jet cross sections and charge correlations are also discussed. We also give analytic formulae for inclusive cross sections in general hard scattering models. Spectator and dimensional counting rules are given which determine the scaling be-
