# Gauged Supergravity from the Lunin-Maldacena background

## TL;DR

This paper develops a consistent truncation of IIB supergravity on a beta-deformed AdS5 x S5 background, connecting it to gauged N=2 supergravity and exploring its relation to Sasaki-Einstein manifolds.

## Contribution

It constructs a full bosonic sector truncation of IIB supergravity on a Lunin-Maldacena background, extending previous solutions and discussing potential generalizations.

## Key findings

- Derived a consistent five-dimensional supergravity truncation.
- Linked the solution to similar constructions on Sasaki-Einstein manifolds.
- Explored possibilities for further generalizations of the Lunin-Maldacena background.

## Abstract

We show how to expand the Lunin-Maldacena solution to the full bosonic sector of gauged $\mathcal N=2$ supergravity. In particular, we construct a consistent truncation of IIB supergravity on a $\beta$-deformed $\mathrm{AdS}_5\times S^5$ background retaining a dynamical metric and graviphoton in five dimensions. We comment on the relation between this solution and similar constructions on Sasaki-Einstein manifolds, as well as the possibility of further consistent truncations which generalize the Lunin-Maldacena solution.
