Supergravity Miracles: Phenomenology with Gravitational Divergences

Abstract

The properties of singlet fields in supergravity background are discussed. Particularly, it is shown that the $\mathcal{O}({\Lambda }^2)$ contributions to their one-point function lead to novel derivations of effective scales such as the $\mu$ parameter, a messenger scale, an intermediate symmetry-breaking scale, and the unification scale, in terms of the scale of spontaneous supersymmetry-breaking in a hidden sector.The singlet one-point function effectively serves as a messenger of supersymmetry breaking.
