Abstract: (Elsevier)
The field theoretical foundations of the light cone perturbation theory, including QCD, are reviewed on the basis of the original papers. Great attention is paid to the systematic account of the spin effects in the light cone scheme. We also emphasize the rôle of the Jacobi relative momenta in giving an invariant formulation of the light cone approach, and proving the cluster decomposition property. These features are very important in the relativistic dynamics of many body systems. There is stressed the existence of the physical vacuum in the light cone approach, which allows to build the Fock space basis. This gives the possibility of formulating systematic approximations to the structure of hadrons. There are given examples of sizable, relativistic, repulsive effects, and there is stressed the presence of a 3-quark irreducible force, which plays an essential rôle in the deep inelastic structure of nucleon, and other nuclei. We show the asymptotic behavior of the elastic electromagnetic form factors of bound states, and indicate, that to account for the deuteron experimental data it is insufficient to treat only the mesonic and nucleonic degrees of freedom (one must go to the quark level).
