Phase transition from hadronic matter to quark matter
P. Wang, A. W. Thomas, A. G. Williams
We study the phase transition from nuclear matter to quark matter within the SU(3) quark mean field model and NJL model. The SU(3) quark mean field model is used to give the equati…
Landau gauge Jacobian and BRST symmetry
M. Ghiotti, A. C. Kalloniatis, A. G. Williams
We propose a generalisation of the Faddeev-Popov trick for Yang-Mills fields in the Landau gauge. The gauge-fixing is achieved as a genuine change of variables. In particular the J…
Curci-Ferrari mass and the Neuberger problem
A. C. Kalloniatis, L. von Smekal, A. G. Williams
We study the massive Curci-Ferrari model as a starting point for defining BRST quantisation for Yang-Mills theory on the lattice. In particular, we elucidate this proposal in light…
QCD, Gauge Fixing, and the Gribov Problem
A. G. Williams
The standard techniques of gauge-fixing, such as covariant gauge fixing, are entirely adequate for the purposes of studies of perturbative QCD. However, they fail in the nonperturb…
Heavy quark distribution functions in heavy baryons
X. -H. Guo, A. W. Thomas, A. G. Williams
Using the Bethe-Salpeter (B-S) equations for heavy baryons Lambda_Q, Sigma_Q, Xi_Q and Omega_Q (Q=b or c), which were established in previous work, we calculate the heavy quark dis…
Regularization-independent studies of nonperturbative field theory
A. Kizilersu, A. W. Schreiber, A. G. Williams
We propose a regularization-independent method for studying a renormalizable field theory nonperturbatively through its Dyson-Schwinger equations. Using QED_4 as an example, we sho…
