An alternative IIB embedding of F(4) gauged supergravity

Abstract

Through the construction of a complete non-linear Kaluza-Klein reduction ansatz from type IIB supergravity to Romans’ F(4) gauged supergravity, we identify a recently discovered supersymmetric AdS6 solution as the IIB uplift of the supersymmetric vacuum of Romans’ theory. We present new IIB uplifts of a number of known solutions of Romans’ theory and comment on supersymmetry in higher-dimensions where it is expected.
