Abstract
Kappen’s ‘‘Λ-space’’ approach to radiative symmetry breaking in supergravity models is discussed. It is shown that this approach does not sum the leading-logarithmic radiative corrections. It is also pointed out that the threshold effects in the conventional renormalization-group (RG) approach are much smaller than apprehended by Kappen. It is finally argued that the threshold effects at the ultrahigh scale cannot be determined in the ‘‘Λ-space’’ approach, and that this definition of scalar masses contains the same ambiguities as the RG approach.
