A Note on Non-Flat Points in the PQ F-Theory Model
Ismail Achmed-Zade, Iñaki García-Etxebarria, Christoph Mayrhofer
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 phenomen…
2d orbifolds with exotic supersymmetry
Ioannis Florakis, Iñaki García-Etxebarria, Dieter Lust +1
We analyse various two dimensional theories arising from compactification of type II and heterotic string theory on asymmetric orbifolds. We find extra supersymmetry generators ari…
8d gauge anomalies and the topological Green-Schwarz mechanism
Iñaki García-Etxebarria, Hirotaka Hayashi, Kantaro Ohmori +2
String theory provides us with 8d supersymmetric gauge theory with gauge algebras , , , , $\mathfrak{e}_{7}…
four dimensional field theories
Iñaki García-Etxebarria, Diego Regalado
We briefly review a class of four dimensional field theories constructed by taking a quotient of SYM with gauge group . The quotient involves a…
Global Orientifolded Quivers with Inflation
Michele Cicoli, Iñaki García-Etxebarria, Christoph Mayrhofer +3
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…
Yukawa couplings in F-theory as D-brane instanton effects
Andres Collinucci, Iñaki García-Etxebarria
In a weak coupling limit the neighborhood of Yukawa points in GUT F-theory models is described by a non-resolvable orientifold of the conifold. We explicitly show, fi…
