Flux and Chiral Matter in SU(5)xU(1) F-Theroy GUT Models and their IIB Analogue |
Speaker: | Christoph Mayrhofer (Heidelberg University) |
Abstract: | In this talk we will describe the construction of a special
class of chirality inducing G_4-fluxes in global F-theory
compactifications on Calabi-Yau four-folds. We will detail this flux
in the case of models with SU(5)xU(1) gauge group which are relevant
in the context of F-theory GUT model building. We will compute the
chiral index of both SU(5) charged matter and of SU(5) singlets
charged only under the U(1). The latter are localised on curves which
are not contained in the SU(5) locus. We also extend our results to
chiral fluxes in models without U(1) restriction and comment on
D-brane recombination between the SU(5) and SU(5)xU(1). As a final
step we take the weak coupling limit and give the IIB interpretation
of these fluxes. |
