Light Front Quantization
An introductory overview on Light-Front quantization, with some emphasis on recent achievements, is given. Light-Front quantization is the most promising and physical tool to study deep inelastic scattering on the basis of quark gluon degrees of freedom. The simplified vacuum structure (nontrivial vacuum effects can only appear in zero-mode degrees of freedom) and the physical basis allows for ...
متن کاملLight-front Quantization and Qcd Phenomena∗
The light-front quantization of QCD provides an alternative to lattice gauge theory for computing the mass spectrum, scattering amplitudes, and other physical properties of hadrons directly in Minkowski space. Nonperturbative light-front methods for solving gauge theory and obtaining light-front wavefunctions, such as discretized light-front quantization, the transverse lattice, and light-front...
متن کاملLight - Front Dynamics and Light - Front Qcd
In this article, I will try to address some aspects of nonperturbative QCD. The theory of nonperturbative QCD (at the hadronic scale) has indeed not been well defined at the present time. Firstly, how much we can understand about the real theory of the strong interaction from the canonical QCD structure is totally unknown. Secondly, there are in the literature many models or effective theories ...
متن کاملLight - Front Quantization of Gauge Theories ∗
Light-front wavefunctions provide a frame-independent representation of hadrons in terms of their physical quark and gluon degrees of freedom. The light-front Hamiltonian formalism provides new nonperturbative methods for obtaining the QCD spectrum and eigensolutions, including resolvant methods, variational techniques, and discretized light-front quantization. A new method for quantizing gauge...
متن کاملFor Review O nly Light Front Quantization
The Dirac procedure for dealing with constraints is applied to the quantization of gauge theories on the light front. The light cone gauge is used in conjunction with the first class constraints that arise and the resulting Dirac brackets are found. These gauge conditions are not used to eliminate degrees of freedom from the action prior to applying the Dirac constraint procedure. This approach...
