AMSB and the logic of spontaneous SUSY breaking

A bstract A cardinal principle of any theory of spontaneous supersymmetry breaking, is that the order parameter is a linear combination of the F and D terms. Also as long as the supersymmetry of the action is preserved at the quantum level, this principle should be valid after the appropriate corrections are incorporated into the Kähler potential, the superpotential, and the gauge coupling functions that define the theory. The claim that in AMSB there is an extra term for the gaugino mass that is proportional to the gravitino mass, is then equivalent to the statement that quantum effects cause an explicit breaking of (local) SUSY. Expanding on previous work, we argue that this arises from confusing the scalar compensator with the density compensator. We also comment on various recent papers on AMSB.
