A Stuckelberg formalism for the gravitino from warped extra dimensions
Tony Gherghetta, Alex Pomarol
TL;DR
This paper explores how supersymmetry breaking via boundary conditions in warped extra dimensions leads to a natural application of the Stuckelberg formalism for the gravitino, ensuring a smooth massless limit in four dimensions.
Contribution
It introduces a novel connection between boundary-condition-induced supersymmetry breaking and the Stuckelberg formalism for the gravitino in warped extra-dimensional models.
Findings
The formalism ensures a smooth massless limit for the gravitino.
Supersymmetry breaking preserves R-symmetry at boundaries.
The approach provides a consistent 4D effective theory.
Abstract
We consider supersymmetric theories with a warped extra dimension where supersymmetry is broken by boundary conditions that preserve an R-symmetry. It is shown that this supersymmetry breaking mechanism naturally invokes the Stuckelberg formalism for the gravitino in order to give a four-dimensional theory with a smooth massless limit.
