We discuss high-p/sub T/ production of particle pairs, comparing the ''higher-twist'' constituent-interchange-model (CIM) subprocesses to the most ''elementary'' (quantum chromodynamics (QCD)) subprocesses. All aspects of spectra scaling laws and charge and quantum-number correlations are discussed. Comparison with existing data is given. In general, we find that meson pairs at moderate p/sub T/ receive contributions from a mixture of QCD and CIM subprocesses; the strongest evidence for the CIM contributions comes from substantial charge correlations observed in several experiments. For pairs involving baryons, especially pp-bar, CIM should be dominant at moderate p/sub T/ with consequent large correlations and strong inverse-p/sub T/ damping.
