Six-Dimensional Superconformal Field Theories from Principal 3-Bundles over Twistor Space

Understand

We construct manifestly superconformal field theories in six dimensions which contain a non-Abelian tensor multiplet.

• In particular, we show how principal 3-bundles over a suitable twistor space encode solutions to these self-dual tensor field theories via a Penrose-Ward transform.
• The resulting higher or categorified gauge theories significantly generalise those obtained previously from principal 2-bundles in that the so-called Peiffer identity is relaxed in a systematic fashion.
• This transform also exposes various unexplored structures of higher gauge theories modelled on principal 3-bundles such as the relevant gauge transformations.
