Abstract

The fermion mass textures are discussed in the context of F‐theory SU(5) GUT. The tree‐level up, down and charged lepton Yukawa couplings are computed in terms of the integrals of overlapping wavefunctions at the intersection points of three matter curves. All remaining entries in the fermion mass matrices can also be reliably estimated from higher order non‐renormalizable Yukawa couplings mediated by heavy string modes and/or Kaluza‐Klein states.

## Abstract F‐theory has the advantage that all the Yukawa couplings of grand unified theories are included and can be computed. The Yukawa couplings of charged matter multiplets are generated around codimension‐3 singularity points of a base but the geometry of F‐theory compactifications is much m

## Abstract This proceeding is based on the paper 1010.5188 [hep‐th] where we discuss SU(5) Grand Unified Theories in the context of orientifold compactifications. Specifically, we investigate three D‐brane stack realizations of the Georgi‐Glashow model and analyze them with respect to their Yukawa
