Exceptional N=3 theories (2017)
Journal Article

We present a new construction of four dimensional N = 3 theories, given by M5 branes wrapping a T 2 in an M-theory U-fold background. The resulting setup generalizes the one used in the usual class S construction of four dimensional theories by using... Read More about Exceptional N=3 theories.

8d gauge anomalies and the topological Green-Schwarz mechanism (2017)
Journal Article
García-Etxebarria, I., Hayashi, H., Ohmori, K., Tachikawa, Y., & Yonekura, K. (2017). 8d gauge anomalies and the topological Green-Schwarz mechanism. Journal of High Energy Physics, 2017(11), Article 177. https://doi.org/10.1007/jhep11%282017%29177

String theory provides us with 8d supersymmetric gauge theory with gauge algebras su(N), so(2N), sp(N), e6, e7 and e8, but no construction for so(2N+1), f4 and g2 is known. In this paper, we show that the theories for f4 and so(2N+1) have a global ga... Read More about 8d gauge anomalies and the topological Green-Schwarz mechanism.

Global Orientifolded Quivers with Inflation (2017)
Journal Article
Cicoli, M., García-Etxebarria, I., Mayrhofer, C., Quevedo, F., Shukla, P., & Valandro, R. (2017). Global Orientifolded Quivers with Inflation. Journal of High Energy Physics, 11, Article 134. https://doi.org/10.1007/jhep11%282017%29134

We describe global embeddings of fractional D3 branes at orientifolded singularities in type IIB flux compactifications. We present an explicit Calabi-Yau example where the chiral visible sector lives on a local orientifolded quiver while non-perturb... Read More about Global Orientifolded Quivers with Inflation.

E6 Yukawa couplings in F-theory as D-brane instanton effects (2017)
Journal Article
Collinucci, A., & García-Etxebarria, I. (2017). E6 Yukawa couplings in F-theory as D-brane instanton effects. Journal of High Energy Physics, 03, Article 155. https://doi.org/10.1007/jhep03%282017%29155

At weak coupling the neighborhood of a E6 Yukawa point in SU(5) GUT F-theory models is described by a non-resolvable orientifold of the conifold. We explicitly show, first directly in IIB and then via a mirror symmetry argument, that in this limit th... Read More about E6 Yukawa couplings in F-theory as D-brane instanton effects.

S-duality in N=1 orientifold SCFTs (2017)
Journal Article
García-Etxebarria, I., & Heidenreich, B. (2017). S-duality in N=1 orientifold SCFTs. Fortschritte der Physik, 65(3-4), https://doi.org/10.1002/prop.201700013

We present a general solution to the problem of determining all S-dual descriptions for a specific (but very rich) class of urn:x-wiley:00158208:media:prop201700013:prop201700013-math-0003 SCFTs. These SCFTs are indexed by decorated toric diagrams, a... Read More about S-duality in N=1 orientifold SCFTs.

Ubiquity of non-geometry in heterotic compactifications (2017)
Journal Article
García-Etxebarria, I., Lust, D., Massai, S., & Mayrhofer, C. (2017). Ubiquity of non-geometry in heterotic compactifications. Journal of High Energy Physics, 03, Article 046. https://doi.org/10.1007/jhep03%282017%29046

We study the effect of quantum corrections on heterotic compactifications on elliptic fibrations away from the stable degeneration limit, elaborating on a recent observation by Malmendier and Morrison. We show that already for the simplest nontrivial... Read More about Ubiquity of non-geometry in heterotic compactifications.
