Paper of Martin Wolf on string field theory appears in J High Energy Physics

The paper “Supersymmetric Yang-Mills theory as higher Chern-Simons theory” co-authored by Christian Saemann (Herriot-Watt) and Martin Wolf has been published in the Journal of High Energy Physics.  The paper is published gold open access, and a link to the published paper is here. In the paper they observe that the string field theory actions for the topological sigma models describe higher or categorified Chern-Simons theories. These theories yield dynamical equations for connective structures on higher principal bundles. As a special case, they consider holomorphic higher Chern-Simons theory on the ambi-twistor space of four-dimensional space-time. In particular, they propose a higher ambi-twistor space action functional for maximally supersymmetric Yang-Mills theory.
