A string and M-theory origin for the Salam-Sugin model Academic Article uri icon


  • An M/string-theory origin for the six-dimensional Salam-Sezgin chiral gauged supergravity is obtained, by embedding it as a consistent Pauli-type reduction of type I or heterotic supergravity on the non-compact hyperboloid H2,2 times S1. We can also obtain embeddings of larger, non-chiral, gauged supergravities in six dimensions, whose consistent truncation yields the Salam-Sezgin theory. The lift of the Salam-Sezgin (Minkowski)4S2 ground state to ten dimensions is asymptotic at large distances to the near-horizon geometry of the NS5-brane. 2003 Elsevier B.V. All rights reserved.
