Gauge fixing and BRST formalism in non-Abelian gauge theories
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 the BRST formalism in Yang-Mills theory. We propose first a model to re-write the Faddeev-Popov quantisation method in terms of grouptheoretical techniques and then we give a possible way to solve the no-go theorem of ...
متن کاملAbelian and center gauge fixing in continuum Yang - Mills - Theory for general gauge groups 1
A prescription for center gauge fixing for pure Yang-Mills theory in the continuum with general gauge groups is presented. The emergence of various types of singular-ities (magnetic monopoles and center vortices) appearing in the course of the gauge fixing procedure are discussed.
متن کاملAbelian and Nonabelian Lattice Chiral Gauge Theories through Gauge Fixing
After an introduction in which we review the fundamental difficulty in constructing lattice chiral gauge theories, we summarize the analytic and numerical evidence that abelian lattice chiral gauge theories can be nonperturbatively constructed through the gauge-fixing approach. In addition, we indicate how we believe that the method may be extended to nonabelian chiral gauge theories.
متن کاملNote on the Gauge Fixing in Gauge Theory
In the absence of Gribov complications, the modified gauge fixing in gauge theory ∫ DAμ{exp[−SYM (Aμ)− ∫ f(Aμ)dx]/ ∫ Dg exp[− ∫ f(Aμ)dx]} for example, f(Aμ) = (1/2)(Aμ) 2, is identical to the conventional Faddeev-Popov formula ∫ DAμ{δ(D δf(Aν ) δAμ )/ ∫ Dgδ(Dμ δf(A g ν ) δA g μ )} exp[−SYM (Aμ)] if one takes into account the variation of the gauge field along the entire gauge orbit. Despite of ...
متن کاملYang-Mills theory as an Abelian theory without gauge fixing
A general procedure to reveal an Abelian structure of Yang-Mills theories by means of a (nonlocal) change of variables, rather than by gauge fixing, in the space of connections is proposed. The Abelian gauge group is isomorphic to the maximal Abelian subgroup of the Yang-Mills gauge group, but not its subgroup. A Maxwell field of the Abelian theory contains topological degrees of freedom of ori...
