Beta Functions of Topologically Massive Supergravity

High Energy Physics - Theory 2015-06-12 v2

Abstract

We compute the one-loop beta functions of the cosmological constant, Newton's constant and the topological mass in topologically massive supergravity in three dimensions. We use a variant of the proper time method supplemented by a simple choice of cutoff function. We find that the dimensionless coefficient of the Chern-Simons term, ν\nu, has vanishing beta function. The flow of the cosmological constant and Newton's constant depends on ν\nu; we study analytically the structure of the flow and its fixed points in the limits of small and large ν\nu.
