Abstract We prove the uniqueness of the supersymmetric Salam–Sezgin (Minkowski) 4 × S 2 ground state among all non-singular solutions with a four-dimensional Poincare, de Sitter or anti-de Sitter symmetry. We construct the most general solutions with an axial symmetry in the two-dimensional internal space, and show that included amongst these is a family that is non-singular away from a conical defect at one pole of a distorted 2-sphere. These solutions admit the interpretation of 3-branes with negative tension.
