Quantum discontinuity between zero and infinitesimal graviton mass with a Lambda term
F. A. Dilkes, M. J. Duff, James T. Liu +1
We show that the recently demonstrated absence of the usual discontinuity for massive spin 2 with a Lambda term is an artifact of the tree approximation, and that the discontinuity…
The Yukawa Coupling in Three Dimensions
F. A. Dilkes, D. G. C. McKeon, K. Nguyen
We consider several renormalizable, scale free models in three space-time dimensions which involve scalar and spinor fields. The Yukawa couplings are bilinear in both the spinor an…
Gauge Dependence in Chern-Simons Theory
F. A. Dilkes, L. C. Martin, D. G. C. McKeon +1
We compute the contribution to the modulus of the one-loop effective action in pure non-Abelian Chern-Simons theory in an arbitrary covariant gauge. We find that the results are de…
A Normal Coordinate Expansion for the Gauge Potential
F. A. Dilkes
In this pedagogical note, I present a method for constructing a fully covariant normal coordinate expansion of the gauge potential on a curved space-time manifold. Although the con…
