Abstract

We consider flux compactifications of heterotic string theory in the presence of fermionic condensates on M1,2 x X7 with both factors carrying a Killing spinor. In other words, M1,2 is either de Sitter, anti-de Sitter or Minkowski, and X7 possesses a nearly parallel G2-structure or has G2-holonomy. We solve the complete set of field equations and the Bianchi identity to order α′. The latter is satisfied via a non-standard embedding by choosing the gauge field to be a G2-instanton. It is shown that none of the solutions to the field equations is supersymmetric.
