TL;DR

This paper derives four-dimensional theories of partial supersymmetry breaking from five-dimensional supergravity using a generalized dimensional reduction with the Scherk-Schwarz mechanism, confirming previous four-dimensional results.

Contribution

It introduces a novel derivation of N=2 to N=1 supersymmetry breaking theories via five-dimensional supergravity and a specific reduction technique.

Findings

The derived theories match previous four-dimensional results.

The approach confirms the consistency of partial supersymmetry breaking from higher dimensions.

Provides a new perspective on dimensional reduction mechanisms.

Abstract

Theories of partial supersymmetry breaking N=2 -> N=1 in four dimensions are derived by coupling the N=2 massless gravitino multiplet to N=2 supergravity in five dimensions and performing a generalized dimensional reduction on S^1/Z_2 with the Scherk-Schwarz mechanism. These theories agree with results that were previously derived from four dimensions.
