Using gauge-invariant variables in QCD
Kurt Haller
The Weyl-gauge ( QCD Hamiltonian is unitarily transformed to a representation in which it is expressed entirely in terms of gauge-invariant quark and gluon fields. In a s…
A Gauge-Invariant Color Charge in QCD
Kurt Haller
A gauge-invariant color-charge operator is defined and related to an integral of the gauge-invariant chromoelectric field over a closed surface. We discuss the case of a surface al…
Dynamics and topology of the gauge-invariant gauge field in two-color QCD
Kurt Haller
A nonlinear integral equation that is responsible for the implementation of the non-Abelian Gauss's law is applied to an investigation of the topological features of two-color QCD…
Nonlocal color interactions in a gauge-invariant formulation of QCD
Kurt Haller, Lusheng Chen
We construct a set of states that implement the non-Abelian Gauss's law for QCD. We also construct a set of gauge-invariant operator-valued quark and gluon fields by establishing a…
Gauge-Invariant QCD - an Approach to Long-Range Color-Confining Forces
Kurt Haller
We discuss the transformation of the QCD temporal-gauge Hamiltonian to a representation in which it can be expressed as a functional of gauge-invariant quark and gluon fields. We s…
