Light - 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 Quantum Chromodynamics
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 Lorentz covariance, leading to the calculation of a renormalized QCD hamiltonian using a similarity renormalization group. Renormalization repairs broken symmetries, and in light-front field theory it mo...
متن کاملLight Front QCD
In these lectures, I survey a number of applications of light-front methods to hadron and nuclear physics phenomenology and dynamics, including light-front statistical physics. Light-front Fock-state wavefunctions provide a frame-independent representation of hadrons in terms of their fundamental quark and gluon degrees of freedom. Nonperturbative methods for computing LFWFs in QCD are discusse...
متن کاملNonperturbative Light-front Methods *
Two methods for the nonperturbative solution of field-theoretic bound-state problems, based on light-front coordinates, are briefly reviewed. One uses Pauli–Villars regularization and the other supersymmetry. Applications to Yukawa theory and super Yang–Mills theory with fundamental matter are emphasized .
متن کاملLight 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 ...
