Heterotic moduli, the double extension and the alpha'^2 metric
Jock McOrist, Qianhe Yin
We compute the heterotic moduli-space metric through for backgrounds admitting a smooth limit. The Kaehler potential is unchanged to this order, but the metric re…
Universal geometry as an organising principle for heterotic moduli
Jock McOrist
A family of heterotic compactifications carries more structure than a collection of solutions parametrised by moduli. Once the compactification data are fibred over moduli space, d…
Stringy Corrections to Heterotic SU(3)-Geometry
Jock McOrist, Sebastien Picard
We analyse the corrections to the supersymmetry transformations constructed by Bergshoeff--de Roo for heterotic compactifications on SU(3) manifolds. The internal geometry r…
The heterotic moduli space metric
Jock McOrist, Martin Sticka, Eirik Eik Svanes
In this article we dimensionally reduce a heterotic supergravity on a background with Minkowski spacetime using a certain cohomology as a basis for the Kaluza-Klein expansion…
The physical moduli of heterotic G_2 string compactifications
Jock McOrist, Martin Sticka, Eirik Eik Svanes
In previous works, an operator was developed for heterotic compactifications on and , which preserves supersymmetry and w…
The moduli of the universal geometry of heterotic moduli
Jock McOrist, Martin Sticka, Eirik Eik Svanes
We study the moduli of the universal geometry of heterotic vacua. Universal geometry refers to a family of heterotic vacua fibered over the moduli space. The universal…
