Abstract

Recently an interesting idea has been put forward by Robinson and Wilczek that the incorporation of quantized gravity in the framework of Abelian and non-Abelian gauge theories results in a correction to the running of gauge coupling and, as a consequence, increase the grand unification scale and asymptotic freedom. In this Letter it is shown by explicit calculations that this correction depends on the choice of gauge.

Gravitational Correction to Running of Gauge Couplings

Robinson, Sean P. ; Wilczek, Frank - Physical Review Letters

We calculate the contribution of graviton exchange to the running of gauge couplings at lowest nontrivial order in perturbation theory. Including this contribution in a theory that features coupling constant unification does not upset this unification, but rather shifts the unification scale. When extrapolated formally, the gravitational correction renders all gauge couplings asymptotically free.

Running couplings and operator mixing in the gravitational corrections to coupling constants

Anber, Mohamed M. ; Department of Physics, University of Massachusetts, Amherst, Massachusetts 01003 ; Donoghue, John F. ; ... - Physical Review. D, Particles Fields

The use of a running coupling constant in renormalizable theories is well known, but the implementation of this idea for effective field theories with a dimensional coupling constant is, in general, less useful. Nevertheless, there are multiple attempts to define running couplings, including the effects of gravity, with varying conclusions. We sort through many of the issues involved, most particularly the idea of operator mixing and also the kinematics of crossing, using calculations in Yukawa and {lambda}{phi}{sup 4} theories as illustrative examples. We remain in the perturbative regime. In some theories with a high permutation symmetry, such as {lambda}{phi}{sup 4},more »« less

Running couplings in equivariantly gauge-fixed SU(N) Yang-Mills theories

Golterman, Maarten ; Shamir, Yigal - Physical Review. D, Particles Fields

In equivariantly gauge-fixed SU(N) Yang-Mills theories, the gauge symmetry is only partially fixed, leaving a subgroup H subset of SU(N) unfixed. Such theories avoid Neuberger's nogo theorem if the subgroup H contains at least the Cartan subgroup U(1){sup N-1}, and they are thus nonperturbatively well defined if regulated on a finite lattice. We calculate the one-loop beta function for the coupling g-tilde{sup 2}={xi}g{sup 2}, where g is the gauge coupling and {xi} is the gauge parameter, for a class of subgroups including the cases that H=U(1){sup N-1} or H=SU(M)xSU(N-M)xU(1). The coupling g-tilde represents the strength of the interaction of themore »« less

Path-integral derivation of gauge and gravitational chiral anomalies in theories with vector and axial-vector couplings in arbitrary even dimensions

Gipson, J.M. - Phys. Rev. D; (United States)

The anomalies associated with general linear transformations of fermions coupled to external vector and axial-vector fields in curved spaces of arbitrary even dimensions are derived within the path-integral framework. The anomalies are due to the noninvariance of the fermionic functional measure under these transformations. The anomalies satisfy the Wess-Zumino consistency conditions. This implies that the choice of the fermionic functional measure is the correct one. Special cases of the general formula obtained agree with all previous results.

Gauge dependence of the. eta. function in Chern-Simons field theory and the Vilkovisky-DeWitt correction

Birmingham, D. ; Cho, H.T. ; Kantowski, R. ; ... - Physical Review, D (Particles Fields); (USA)

We use two one-parameter families of gauges to demonstrate the gauge dependence of {eta}(0) for quantized pure Chern-Simons field theory on {ital R}{sup 3}. The first family consists of local covariant gauges and all reproduce the Landau-DeWitt gauge result. The second family consists of nonlocal and noncovariant gauges which produce gauge-dependent results not proportional to the original background Chern-Simons action. However, when the one-loop quantum operators for these gauges are corrected by adding the appropriate Vilkovisky-DeWitt term, the gauge dependence is removed. All functional traces are evaluated using two methods, a momentum expansion and a covariant perturbation similar to themore »« less
