Abstract
The application of perturbative quantum chromodynamics to the dynamics of hadrons at short distance is reviewed, with particular emphasis on the role of the hadronic bound state. A number of new applications are discussed, including (a) the modification to QCD scaling violations in structure functions due to hadronic binding (b) a discussion of coherence and binding corrections to the gluon and sea‐quark distributions; (c) QDC radiative corrections to dimensional counting rules for exclusive processes and hadronic form factors at large momentum transfer; (d) generalized counting rules for inclusive processes; (e) the special role of photon‐induced reactions in QCD, specially applications to jet production in photon–photon collisions, and photon production at large transverse momentum. We also present a short review of the central problems in large PT hadronic reactions and the distinguishing characteristics of gluon and quark jets.
