Limitation on Magnitude of $D$-components

Abstract

We study the magnitude of $D$-components in a generic supersymmetric field theory. There exists $F$-component whose vacuum expectation value is comparable to or bigger than that of $D$-component, in the absence of Fayet-Iliopoulos term, the large hierarchy in the charge spectrum and strongly interacting higher-dimensional couplings in the Kähler potential, if contributions from other terms than $F$ and $D$-terms are negligible.
