Abstract

In this article we dimensionally reduce a heterotic supergravity on a G2G_2 background with Minkowski spacetime using a certain cohomology as a basis for the Kaluza-Klein expansion, up to and including first order in α\alpha'. We construct the moduli space heterotic G2G_2 compactifications. The α\alpha'-correction induces a curvature correction to the Weyl-Peterson metric. In the limit in which the G2G_2 manifold reduces to SU(3)SU(3), we recover known results.
