Heterotic horizons and AdS backgrounds that preserve 6 supersymmetries
Georgios Papadopoulos
We prove, under suitable global assumptions, that the only heterotic horizons with closed 3-form field strength that preserve strictly 6 supersymmetries have spatial horizon sectio…

W-symmetries, anomalies and heterotic backgrounds with non-compact holonomy
G. Papadopoulos, J. Phillips
We determine the algebra of holonomy symmetries of sigma models propagating on supersymmetric heterotic backgrounds with a non-compact holonomy group. We demonstrate that these clo…
