Abstract

The effective action in four dimensions resulting from the ten‐dimensional 𝒩 = 1 heterotic supergravity coupled to 𝒩 = 1 supersymmetric Yang‐Mills upon dimensional reduction over nearly‐Kähler manifolds is discussed. Nearly‐Kähler manifolds are an interesting class of manifolds admitting an SU(3)‐structure and in six dimensions all homogeneous nearly‐Kähler manifolds are included in the class of the corresponding non‐symmetric coset spaces plus a group manifold. Therefore it is natural to apply the Coset Space Dimensional Reduction scheme using these coset spaces as internal manifolds in order to determine the four‐dimensional theory.

## Abstract We study the dimensional reduction of the 𝒩 = 1, ten‐dimensional Heterotic Supergravity to four dimensions, at leading order in α', when the internal space is a nearly‐Kähler manifold. Nearly‐Kähler manifolds in six dimensions are all the non‐symmetric coset spaces and a group manifold.
