  title={Hitchin Functionals in N = 2 Supergravity},
  author={Mariana Gra{\~n}a and Jan Louis and Daniel Waldram},
We consider type II string theory in space-time backgrounds which admit eight supercharges. Such backgrounds are characterized by the existence of a (generically nonintegrable) generalized SU (3)×SU (3) structure. We demonstrate how the corresponding ten-dimensional supergravity theories can in part be rewritten using generalised O(6, 6)covariant fields, in a form that strongly resembles that of four-dimensional N = 2 supergravity, and precisely coincides with such after an appropriate Kaluza… CONTINUE READING
