# Supersymmetric IIB Background with AdS_4 Vacua from Massive IIA Supergravity

## TL;DR

This paper constructs a new supersymmetric Type IIB supergravity background with AdS4 vacua by applying non-Abelian T-duality to a massive IIA solution, including all fluxes and a non-trivial dilaton and B-field.

## Contribution

It introduces a novel supersymmetric AdS4 background in Type IIB supergravity derived from massive IIA via non-Abelian T-duality, with explicit Killing spinor construction.

## Key findings

- The background preserves supersymmetry.
- All fluxes and fields are explicitly turned on.
- The solution expands the landscape of AdS4 vacua in supergravity.

## Abstract

We present a new Type IIB supergravity background of the warped form AdS$_4\times \mathcal{M}_6$ with dilaton, $B$-field and all Ramond-Ramond fluxes turned on. We obtain the solution by applying non-Abelian T-duality to a certain representative of a class of AdS$_4$ backgrounds in massive IIA supergravity. By explicitly constructing the Killing spinor of the seed solution and using an argument involving Kosmann spinorial Lie derivative we demonstrate that the background is supersymmetric.
