TL;DR
This paper explores a novel mechanism for supersymmetry breaking where the deformation of spacetime geometry, caused by a bulk scalar field, mediates SUSY breaking, with a systematic derivation of the effective action in a 3D superfield framework.
Contribution
It introduces a new geometric approach to SUSY breaking mediated by scalar field backreaction, providing a systematic superfield-based derivation of the effective action.
Findings
Demonstrates geometry-mediated SUSY breaking in a 4D bulk model.
Provides a systematic superfield formulation of the 3D effective action.
Highlights the role of scalar field backreaction in SUSY breaking mechanisms.
Abstract
We investigate SUSY breaking mediated through the deformation of the spacetime geometry due to the backreaction of a nontrivial configuration of a bulk scalar field. To illustrate its features, we work with a toy model in which the bulk is four dimensions. Using the superconformal formulation of SUGRA, we provide a systematic method of deriving the 3D effective action expressed by the superfields.
