Abstract
The mechanisms of hadron scattering at high energies are reviewed in an introductory fashion, but from a modern standpoint in which the authors try to combine the ideas of the parton model and quantum chromodynamics (QCD) with Regge theory and phenomenology. After a brief introduction to QCD and the basic features of hadron scattering data, the authors discuss scaling and the dimensional counting rules, the parton structure of hadrons, and the parton model for large momentum transfer processes, including scaling violations. Hadronic jets and the use of parton ideas in soft scattering processes are examined, and the authors then turn their attention to Regge theory and its applications in exclusive and inclusive reactions, stressing the relationship to parton exchange. The mechanisms of hadron production which build up cross-sections, and hence the underlying Regge singularities, and the possible overlap of Regge and scaling regions are discussed. The key to understanding hadron reaction mechanisms seems to lie in the marriage of Regge theory with QCD.Keywords
