We discuss the origin of the choice of global structure for six dimensional (2, 0) theories and their compactifications in terms of their realization from IIB string theory on ALE spaces. We find that the ambiguity in the choice of global structure o... Read More about IIB flux non-commutativity and the global structure of field theories.

Dai-Freed anomalies in particle physics (2019)
Journal Article
García-Etxebarria, I., & Montero, M. (2019). Dai-Freed anomalies in particle physics. Journal of High Energy Physics, 2019(8), Article 3. https://doi.org/10.1007/jhep08%282019%29003

Anomalies can be elegantly analyzed by means of the Dai-Freed theorem. In this framework it is natural to consider a refinement of traditional anomaly cancellation conditions, which sometimes leads to nontrivial extra constraints in the fermion spect...

A note on non-flat points in the SU(5) × U(1)PQ F-theory model (2019)
Journal Article
Achmed-Zade, I., García-Etxebarria, I., & Mayrhofer, C. (2019). A note on non-flat points in the SU(5) × U(1)PQ F-theory model. Journal of High Energy Physics, 2019(5), Article 13. https://doi.org/10.1007/jhep05%282019%29013

Non-flat fibrations often appear in F-theory GUT models, and their interpretation is still somewhat mysterious. In this note we explore this issue in a model of particular phenomenological interest, the global SU(5) × U(1) Peccei-Quinn F-theory model...
