Paper of Daniele Farotti and Jan Gutowski published in Classical and Quantum Gravity

The paper “Supersymmetry enhancement of heterotic horizons“, co-authored by Daniele Farotti and Jan Gutowski, has been published open access (link here) in the January 2022 issue of Classical and Quantum gravity. The paper considers the near horizon region of supersymmetric extremal black holes in ten-dimensional heterotic supergravity. It investigates the necessary and sufficient conditions for supersymmetry enhancement of such geometries, and constructs the first example of a solution which has the minimal possible amount of supersymmetry.
