Multiscale renormalization group methods for effective potentials with multiple scalar fields

Multiscale renormalization group (RG) methods are reviewed and applied to the analysis of the effective potential for radiative symmetry breaking with multiple scalar fields, allowing an extension of the Gildener and Weinberg method beyond the weak coupling limit. A model containing two interacting...
