Scherk-Schwarz SUSY breaking from the viewpoint of 5D conformal supergravity
Abstract
We reinterpret the Scherk-Schwarz (SS) boundary condition for SU(2)R in a compactified five-dimensional (5D) Poincare supergravity in terms of the twisted SU(2)U gauge fixing in 5D conformal supergravity. In such translation, only the compensator hypermultiplet is relevant to the SS twist, and various properties of the SS mechanism can be easily understood. Especially, we show the correspondence between the SS twist and constant superpotentials within our framework.
