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 کاملPolarized Parton Distributions in Light-front Dynamics
We present a consistent calculation of the structure functions within a light-front constituent quark model of the nucleon. Relativistic effects and the relevance of the covariance constraints are analyzed for polarized parton distributions. Various models, which differ in their gluonic structure at the hadronic scale, are investigated. The results of the full covariant calculation are compared...
متن کاملVacuum Structures in Hamiltonian Light-Front Dynamics
Hamiltonian light-front dynamics of quantum fields may provide a useful approach to systematic non-perturbative approximations to quantum field theories. We investigate inequivalent Hilbert-space representations of the light-front field algebra in which the stability group of the light-front is implemented by unitary transformations. The Hilbert space representation of states is generated by th...
متن کاملLight-Front Dynamics and Generalized Parton Distributions
High energy reactions necessarily involve large momentum transfer to the target’s constituents, which thus rebound near light speed. The experimentally observed correlation between initial and final states measures the system’s response along the light cone. A convenient theoretical description of such reactions is light-front dynamics where the properties of physical states are described along...
متن کاملPolarized parton distributions and Light-Front Dynamics
We present a consistent calculation of the polarized structure functions within a light-front covariant quark model of the nucleon. We analyze the effect of relativity in the momentum distributions and discuss its relevance for the structure functions by recalling previous calculations using non-relativistic models. We show explicit calculations of the polarized gluon distribution in various mo...
