On Restricting to One Loop Order the Radiative Effects in Quantum Gravity
F. T. Brandt, J. Frenkel, D. G. C. McKeon
The dimensionful nature of the coupling in the Einstein-Hilbert action in four dimensions implies that the theory is non-renormalizable; explicit calculation shows that beginning a…
Renormalisation of a diagonal formulation of first order Yang-Mills theory
F T Brandt, J Frenkel, D G C McKeon
We study the BRST renormalization of an alternative formulation of the Yang-Mills theory, where the matrix-propagator of the gluon and the complementary fields is diagonal. This pr…
A Systematic Expansion of Running Couplings and Masses
F. A. Chishtie, D. G. C. McKeon, T. N. Sherry
As an alternative to directly integrating their defining equations to find the running coupling and the running mass , we expand these quantities in powers of $\ln\lef…
The Renormalization Group and the Effective Potential in the Wess-Zumino model
D. G. C. McKeon
We consider the effective potential V in the massless Wess-Zumino model. By using the renormalization group equation, we show that the explicit dependence of V on the renormalizati…
The Non-Abelian Gauge Field Propagator in a Plane Wave Background Field
D. G. C. McKeon
Employing methods introduced by Schwinger in quantum electrodynamics, we compute the propagator for a non-Abelian gauge field in a plane wave background field. In the long distance…
Supersymmetry and the Rotation Group
D. G. C. McKeon
A model invariant under a supersymmetric extension of the rotation group O(3) is mapped, using a stereographic projection, from the spherical surface S2 to two dimensional Euclidea…
