Anomaly mediation from the Randall-Sundrum to the Dine-Seiberg formalism

Abstract

In this paper we reconsider the derivation of anomaly mediated supersymmetry breaking. We work in a general formalism where the $F$ term of the conformal compensator superfield is arbitrary. This allows for a continuous interpolation between the original derivation and a more recent Dine-Seiberg derivation of anomaly mediation. We show that the physical soft parameters are independent of the compensator $F$ term and results of two formalisms agree. Finally, we discuss the role of supersymmetric and nonsupersymmetric thresholds in the effective low-energy Lagrangian as well as the effects of explicit small mass parameters (such as $\ensuremath{\mu}$ term) on the superpartner spectrum.
