Abstract
We find a curious duality between the bosonic sector of heterotic supergravity and the noncritical bosonic string with conformal anomaly. This allows us to map the Mink_4×S^3×S^3 vacuum of the bosonic string to a new warped R×(T1,1×Mink_4) vacuum of the heterotic theory, which turns out to be supersymmetric, preserving 1/4 of the supersymmetry. We perform consistent dimensional reduction of the heterotic theory on the warped R×T1,1 internal space and obtain N = 1, D = 4 supergravity, with one complex scalar multiplet and SU(2)×SU(2) Yang-Mills multiplets, where the gauge symmetry is originated from the isometry group of T1,1.
