Quarks in Coulomb gauge perturbation theory
C. Popovici, P. Watson, H. Reinhardt
Coulomb gauge quantum chromodynamics within the first order functional formalism is considered. The quark contributions to the Dyson-Schwinger equations are derived and one-loop pe…
Coulomb gauge confinement in the heavy quark limit
C. Popovici, P. Watson, H. Reinhardt
The relationship between the nonperturbative Green's functions of Yang-Mills theory and the confinement potential is investigated. By rewriting the generating functional of quantum…
A Bethe--Salpeter Description of Light Mesons
H. Weigel, R. Alkofer, P. Watson
We present a covariant approach to describe the low--lying scalar, pseudoscalar, vector and axialvector mesons as quark--antiquark bound states.This approach is based on an effecti…
The quantum state vector in phase space and Gabor's windowed Fourier transform
A. J. Bracken, P. Watson
Representations of quantum state vectors by complex phase space amplitudes, complementing the description of the density operator by the Wigner function, have been defined by apply…
Completing Continuum Coulomb Gauge in the Functional Formalism
P. Watson, H. Reinhardt
It is argued that within the continuum functional formalism, there is no need to supply a further (spatially independent) gauge constraint to complete the Coulomb gauge of Yang-Mil…
Three-quark confinement potential from the Faddeev equation
C. Popovici, P. Watson, H. Reinhardt
In the heavy quark limit of Coulomb gauge QCD and by truncating the Yang-Mills sector to include only dressed two-point functions, an analytic nonperturbative solution to the Fadde…
