A Note on Heterotic Dualities via M-theory

TL;DR

This paper explores dualities between torsional and Kahler heterotic string compactifications, utilizing a new heterotic c-map analogue to deepen understanding of string dualities.

Contribution

It introduces a novel duality between torsional and Kahler heterotic compactifications based on a recently proposed heterotic c-map analogue.

Findings

Torsional heterotic compactifications are dual to Kahler heterotic compactifications.

The heterotic c-map analogue is key to establishing this duality.

The results expand the understanding of heterotic string dualities.

Abstract

We show that a class of torsional compactifications of the heterotic string are dual to conventional Kahler heterotic string compactifications. This observation follows from the recently proposed analogue of the c-map for the heterotic string.
