E 6 Yukawa couplings in F-theory as D-brane instanton effects

E 6 Yukawa couplings in F-theory as D-brane instanton effects

Abstract At weak coupling the neighborhood of a E 6 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 the E 6 Yukawa coupling is better describe...
