Abstract
We recover the general form of the one-loop effective potential for a Ar 4 theory, nonminimally coupled to a constant-curvature background geometry, in the low-energy limit, i.e. for small curvature. Renormalization is carried out and the massless limit of the renormalized theory is performed. Then we study the symmetry properties of the vacuum state according to the value of the nonminimal coupling constant ~ and the sign of the curvature.File in questo prodotto:
