Unitarity and Lorentz in variance in QCD for a variety of gauges
A. Andrasi, J. C. Taylor
We generalise the Kugo and Ojima formalism henceforth called KO) for the structure of state space in gauge theories, in four respects:- (i) We allow for a more general class of gau…
Generating functions for anti-canonical transformations in the Zinn-Justin and Batalin and Vilkoviski formalisms
A Andrasi, J C Taylor
Quantization of gauge fields by the BRST method requires sources in addition to fields, and a bilinear anti-bracket defined in terms of them. This bracket is a sort of generalizati…
Renormalization in a Landau to Coulomb interpolating gauge in Yang-Mills theory
A Andrasi, J C Taylor
The Coulomb gauge in QCD is the only explicitly unitary gauge. But it suffers from energy-divergences which means that it is not rigorously well-defined. One way to define it unamb…
Renormalization in an interpolating gauge in Yang-Mills theory
A. Andra\V{s}i, J. C. Taylor
The Coulomb gauge in QCD is the only explicitly unitary gauge. But it suffers from energy-divergences which means that it is not rigorously well-defined. One way to define it unamb…
Coulomb gauge QCD from flow gauge at three loops
A Andrasi, J C Taylor
We study the consistency of the non-Abelian Coulomb gauge. There are energy divergences in individual diagrams, which are known to cancel at 2-loop order when suitable sets of diag…
BRST invariance in Coulomb gauge QCD
A. Andrasi, J. C. Taylor
In the Coulomb gauge, the Hamiltonian of QCD contains terms of order h^2, identified by Christ and Lee, which are non-local but instantaneous. The question is addressed how these t…
Finiteness of the Coulomb gauge QCD perturbative effective action
A. Andrasi, J. C. Taylor
At 2-loop order in the Coulomb gauge, individual Feynman graphs contributing to the effective action have energy divergences. It is proved that these cancel in suitable combination…
The effective action in Coulomb gauge QCD
A. Andrasi, J. C. Taylor
At 2-loop order, Feynman integrals in the Coulomb gauge are divergent over the internal energy variables. Nevertheless, it is known how to calculate the effective action provided t…
Linear energy divergences in Coulomb gauge QCD
A. Andrasi
The structure of linear energy divergences is analysed on the example of one graph to 3-loop order. Such dangerous divergences do cancel when all graphs are added, but next to lead…
Renormalization in Coulomb gauge QCD
A. Andrasi, J. C. Taylor
In the Coulomb gauge of QCD, the Hamiltonian contains a non-linear Christ-Lee term, which may alternatively be derived from a careful treatment of ambiguous Feynman integrals at 2-…
Renormalization of Hamiltonian QCD
A. Andrasi, J. C. Taylor
We study to one-loop order the renormalization of QCD in the Coulomb gauge using the Hamitonian formalism. Divergences occur which might require counter-terms outside the Hamiltoni…
Cancellation of energy-divergences in Coulomb gauge QCD
A. Andraši, J. C. Taylor
In the Coulomb gauge of nonabelian gauge theories there are in general, in individual graphs, 'energy-divergences' on integrating over the loop energy variable for fixed loop momen…
The Gluon Propagator in the Coulomb Gauge
A. Andraši
We give the results for all the one-loop propagators, including finite parts, in the Coulomb gauge. In finite parts we find new non-rational functions in addition to the single log…
Renormalization of Wilson Operators in the Light-Cone Gauge
A. Andrasi
We test the renormalization of Wilson operators and the Mandelstam- Leibbrandt gauge in the case when the sides of the loop are parallel to the n, n* vectors used in the M-L gauge.…
New Features of the Mandelstam-Leibbrandt Lightcone Gauge
A. Andrasi
This is about new unexpected features of the Mandestam-Leibbrandt prescription found as applied to spacelike Wilson lines. The regularization parameter in the M-L denominator…
