Holographic dual of the Ω -background

We find an explicit supergravity background dual to the Ω-deformation of a four-dimensional N=2 superconformal field theory (SCFT) on R4. The solution can be constructed in the five-dimensional N=4+ gauged supergravity and has a nontrivial self-dual 2-form. When uplifted to type IIB supergravity the background is a deformation of AdS5×S5 which preserves 16 supercharges. We also discuss generalizations of this solution corresponding to turning on a vacuum expectation value for a scalar operator in the dual SCFT.
