The light-front (LF) canonical quantization of quantum chromodynamics in covariant gauges is discussed. The Dirac procedure is used to eliminate the constraints in the gauge-fixed front form theory quantum action and to construct the LF Hamiltonian formulation. The physical degrees of freedom emerge naturally. The propagator of the dynamical ${\ensuremath{\psi}}_{+}$ part of the free fermionic propagator in the LF quantized field theory is shown to be causal and not to contain instantaneous… 

QCD on the Light-Front

Light-front Hamiltonian theory, derived from the quantization of the QCD Lagrangian at fixed light-front time x+ = x0 + x3, provides a rigorous frame-independent framework for solving nonperturbative

Canonical formulation of light-front gluodynamics and quantization of non-Abelian plane waves

Without gauge fixing, canonical variables for the light-front SU(2) gluodynamics are determined. The Gauss law is written in terms of the canonical variables. The system is qualified as a generalized

QCD and Light-Front Dynamics

AdS/QCD, the correspondence between theories in a dilaton-modified five-dimensional anti-de Sitter space and confining field theories in physical space-time, provides a remarkable semiclassical model

AdS/QCD and Applications of Light-Front Holography

Light-front holography leads to a rigorous connection between hadronic amplitudes in a higher dimensional anti-de Sitter (AdS) space and frame-independent light-front wavefunctions of hadrons in (3 +

Light-Front Holography and the Light-Front SCHRÖDINGER Equation

One of the most important nonperturbative methods for solving QCD is quantization at fixed light-front time τ = t + z/c – Dirac's "Front Form". The eigenvalues of the light-front QCD Hamiltonian

The common elements of atomic and hadronic physics

Atomic physics and hadronic physics are both governed by the Yang Mills gauge theory Lagrangian; in fact, Abelian quantum electrodynamics can be regarded as the zero-color limit of quantum

Hamiltonian, path integral and BRST formulations of large $$N$$N scalar QCD$$_{2}$$2 on the light-front and spontaneous symmetry breaking

Recently Grinstein, Jora, and Polosa have studied a theory of large-$$N$$N scalar quantum chromodynamics in one space and one time dimension. This theory admits a Bethe–Salpeter equation describing

Light-Cone Quantization: Foundations and Applications

These lecture notes review the foundations and some applications of light-cone quantization. First I explain how to choose a time in special relativity. Inclusion of Poincare invariance naturally

Light-front quantum chromodynamics may lead to an accurate constituent approximation for the low-energy properties of hadrons. This requires a cutoff that violates explicit gauge invariance and
