The authors describe an application of the method of the effective potential to a model theory of gravity with independent vierbein and O (1, 3) connection. Adopting a kind of mean field approximation, they find that a Coleman-Weinberg effects occurs: radiative corrections due to loops of the gauge field generate an effective potential for the vierbein whose absolute minimum corresponds to Minkowski space.

Abstract
The authors describe an application of the method of the effective potential to a model theory of gravity with independent vierbein and O (1, 3) connection. Adopting a kind of mean field approximation, they find that a Coleman-Weinberg effects occurs: radiative corrections due to loops of the gauge field generate an effective potential for the vierbein whose absolute minimum corresponds to Minkowski space.File in questo prodotto:
