2004 Review of Light Cone Field Theory

Abstract

This article on light cone field theory reviews the basic concepts of the Poincare group in light cone quantum mechanics and light cone field theory. It discusses recent progress in light cone representations of the Bethe-Salpeter equation, with application to the pion form factor, and the quark Schwinger-Dyson equation. Applications are discussed for deeply virtual Compton scattering, particularly for skewed parton distributions of the pion, and rare B to lepton pair decays. Meson light cone wave functions and recent experimental studies of light cone wave functions are discussed. This review was motivated by the LANL Light Cone 2002 International Workshop.
