Superpotential of three dimensional N $$ \mathcal{N} $$ = 1 heterotic supergravity by Xenia de Ia Ossa, Magdalena Larfors, Matthew Magill, Eirik E. Svanes

“…Abstract We dimensionally reduce the ten dimensional heterotic supergravity action on spacetimes of the form M $$ \mathcal{M} $$ (1, 2) x Y, where M $$ \mathcal{M} $$ (1, 2) is three dimensional maximally symmetric Anti de Sitter or Minkowski space, and Y is a compact seven dimensional manifold with G2 structure. In doing so, we derive the real superpotential functional of the corresponding three dimensional N $$ \mathcal{N} $$ = 1 theory. …”
