RELATIVISTIC BOUND-STATES OF ELEMENTARY-PARTICLES IN LIGHT-FRONT HAMILTONIAN APPROACH TO QUANTUM-FIELD THEORY

This paper explains the light-front Hamiltonian approach to relativistic bound state dynamics of elementary particles in quantum field theory. The paper is an introduction to this emerging theoretical area and reports on the recent progress. A selected set of papers is reviewed. Special attention is paid to renormalization which assumes a central role in the light-front Hamiltonian formalism for quantum chromodynamics.
