- Enhanced gauge symmetry in 6D F-theory models and tuned elliptic Calabi-Yau threefolds (pages 581–644)

The article gives an analysis of the local combinations of gauge groups and matter that can arise in 6D F-theory models over a fixed base. the authors compare the low-energy constraints of anomaly cancellation to explicit F-theory constructions using Weierstrass and Tate forms, and identify some new local structures in the “swampland” of 6D supergravity and SCFT models that appear consistent from low-energy considerations but do not have known F-theory realizations. To illustrate the utility of these results, the authors identify some large example classes of known CY threefolds in the Kreuzer-Skarke database as Weierstrass models over complex surface bases with specific simple tunings.

- Higher groupoid bundles, higher spaces, and self-dual tensor field equations (pages 674–717)

The authors develop a description of higher gauge theory with higher groupoids as gauge structure from first principles. This approach captures ordinary gauge theories and gauged sigma models as well as their categorifications on a very general class of (higher) spaces comprising presentable differentiable stacks, as e.g. orbifolds. The article starts off with a self-contained review on simplicial sets as models of (∞,1) -categories. After discussing principal bundles in terms of simplicial maps and their homotopies, a differentiation procedure mapping higher groupoids to L∞-algebroids is explained in detail. Generalising this procedure, connections for higher groupoid bundles are defined. As an application, one obtains six-dimensional superconformal field theories via a Penrose -Ward transform of higher groupoid bundles over a twistor space. This construction reduces the search for non-Abelian self-dual tensor field equations in six dimensions to a search for the appropriate (higher) gauge structure. The treatment aims to be accessible to theoretical physicists.
