Abstract

The global colour model (GCM) of QCD is a quark-gluon quantum field theory that very successfully models QCD for low energy hadronic processes. An effective gluon correlator models the interaction between quark currents. Functional integral calculus allows the GCM to be hadronised. The dominant configuration of the hadronic functional integrals is revealed to be the constituent quark effect, and is identical to the truncated quark Dyson-Schwinger equations (tDSE). However the GCM shows that hadronic physics requires processes that go beyond the tDSE. In this review examples of meson and nucleon processes are given. The GCM also plays a pivotal role in showing how QCD may be related to many other hadronic models.
