Multiple Gauge Fixing Conditions
D. G. C. McKeon
We consider how more than one gauge fixing condition can be accommodated within the Feynman path integral both by extending the Faddeev-Popov procedure and the BV approach. The fir…
Multi-scale Renormalization Group Methods for Effective Potentials with Multiple Scalar Fields
T. G. Steele, Zhi-Wei Wang, D. G. C. McKeon
Multi-scale renormalization group (RG) methods are reviewed and applied to the analysis of the effective potential for radiative symmetry breaking with multiple scalar fields, allo…
The Effective Potential in Non-Conformal Gauge Theories
F. T. Brandt, F. A. Chishtie, D. G. C. McKeon
By using the renormalization group (RG) equation it has proved possible to sum logarithmic corrections to quantities that arise due to quantum effects in field theories. In particu…
Ghosts from Ghosts in the BRST Formalism
D. G. C. McKeon
We show that the Hamiltonian HQ introduced in the course of BRST analysis of a gauge theory may in fact be associated with an action that itself is gauge invariant. This action can…
The Canonical Structure of the Superstring Action
F. A. Chishtie, D. G. C. McKeon
We consider the canonical structure of the Green-Schwarz superstring in dimensions using the Dirac constraint formalism; it is shown that its structure is similar to that o…
