Scalar field effective action for the spontaneous symmetry breaking in gravity
Abstract
In this paper, we obtain the quantum effective action for a scalar field which has been used for a special kind of symmetry breaking in gravity. Precisely by making use of some renormalization conditions, we calculate the one-loop path integral of canonical momentum. Moreover, we show that by introducing some new renormalization conditions, one can redefine the new degrees of freedom corresponding to a massive vector field.
