Decontracted double BRST on the lattice
Lorenz von Smekal, Marco Ghiotti, Anthony G Williams
We present the Curci-Ferrari model on the lattice. In the massless case the topological interpretation of this model with its double BRST symmetry relates to the Neuberger 0/0 prob…
Gauge fixing and BRST formalism in non-Abelian gauge theories
Marco Ghiotti
In this Thesis we present a comprehensive study of perturbative and non-perturbative non-Abelian gauge theories in the light of gauge-fixing procedures, focusing our attention on t…
Extended Double Lattice BRST, Curci-Ferrari Mass and the Neuberger Problem
M. Ghiotti, L. von Smekal, A. G. Williams
We present Extended Double BRST on the lattice and extend the Neuberger problem to include the ghost/anti-ghost symmetric formulation of the non-linear covariant Curci-Ferrari (CF)…
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…
