Five-Dimensional Gauged Supergravities with Universal Hypermultiplet and Warped Brane Worlds

TL;DR

This paper develops a five-dimensional gauged supergravity model with a universal hypermultiplet, incorporating branes and warped geometries, and analyzes its solutions and Kaluza-Klein spectrum.

Contribution

It introduces a supersymmetric five-dimensional supergravity framework with hypermultiplets and branes, extending to smooth geometries and providing KK mode spectra.

Findings

The model admits the Randall-Sundrum solution as a BPS vacuum.

All KK-tower modes for the model's fields are explicitly derived.

The construction includes auxiliary fields for a smooth geometric description.

Abstract

We present five dimensional gauged supergravity with universal hypermultiplet on M_4 \times S^1 / Z_2 coupled supersymmetrically to three-branes located at the fixed points. The construction is extended to the smooth picture with auxiliary singlet and four-form fields. The model admits the Randall-Sundrum solution as a BPS vacuum with vanishing energy. We give the form of all KK-tower modes for fields present in the model.
