GUT Scale Unification in Heterotic Strings
arXiv:1812.06915 · doi:10.1016/j.physletb.2018.12.054
Abstract
We present a class of heterotic compactifications where it is possible to lower the string unification scale down to the GUT scale, while preserving the validity of the perturbative analysis. We illustrate this approach with an explicit example of a four-dimensional chiral heterotic vacuum with N=1 supersymmetry.
