Abstract

In the paper arXiv:2501.04771, a novel compactification of heterotic supergravity on a warped product of \R× T^1,1 was constructed, where T^1,1 is a five-dimensional coset space (SU(2)× SU(2))/U(1). It was shown that this admits a four dimensional Minkowski vacuum solution with \cal N=1 supersymmetry, and furthermore that in the bosonic sector there exists a remarkable fully consistent truncation in which the gauge bosons of the SU(2)× SU(2) isometries of the T^1,1 are retained. In this paper, we examine this reduction further, and show that the consistency can be extended to include the fermionic sector also. Thus the heterotic theory admits a consistent reduction to give an ungauged \cal N=1 supergravity coupled to SU(2)× SU(2) Yang-Mills multiplets and a scalar multiplet.
