The Gauge-Fixing Fermion in BRST Quantisation
Conditions which must be satisfied by the gauge-fixing fermion χ used in the BRST quantisation of constrained systems are established. These ensure that the extension of the Hamiltonian by the gaugefixing term [Ω, χ] (where Ω is the BRST charge) gives the correct path integral. In canonical BRST quantisation (particularly the path-integral approach developed by Batalin, Fradkin, Fradkina and Vi...

متن کاملBRST operator quantisation of parametrised gauge systems
The BRST quantisation of a finite dimensional gauge system featuring a Hamiltonian constraint quadratic in the momenta reveals that the presence of a potential term and/or additional linear constraints lead to a factor ordered kinetic term in the Hamiltonian which differs from the naively expected Laplacian. This unexpected factor ordering is found to be a necessary condition to obtain constrai...
متن کاملIntegrable hierarchies from BRST-anti-BRST gauge-fixing
The BRST formulation is used in order to derive the existence criterion for classical bi-Hamiltonian systems, based on non-anomalous deformation of the gauge-fixing structure. The recursion operator is then used to provide the entire hierarchy of integrable models associated to the original BRST and anti-BRST charges.
متن کاملGauge 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 ...
