Abstract
A review of NN interaction models is presented starting from perturbative and nonperturbative qq interactions in QCD. Spin structure of baryons and mesons is compared and mechanism of spin-orbit cancellation in excited baryons is explained. Classification of quark and gluon exchanges in NN at high and low energies is given, and the Pomeron structure is elaborated as a two-gluon glueball, by inspecting recently computed glueball Regge-trajectories, The quark potential models of NN interaction with and without Quark Compound Bag (QCB) are discussed and the quark origin of the short-range NN repulsion is reviewed. The NN spin effects are discussed in meson exchanges, Regge-analysis and quark potential models.
