Towards a Realistic F-theory GUT
James C. Callaghan, Stephen F. King, George K. Leontaris +1
We consider semi-local F-theory GUTs arising from a single E_8 point of local enhancement, leading to simple GUT groups based on E_6, SO(10) and SU(5) with SU(3), SU(4) and SU(5) s…
Yukawa couplings in F-theory SU(5)
G. K. Leontaris
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…
On the GUT scale of F-Theory SU(5)
G. K. Leontaris, N. D. Vlachos
In F-theory GUTs, threshold corrections from Kaluza-Klein massive modes arising from gauge and matter multiplets play an important role in the determination of the weak mixing angl…
Knitting neutrino mass textures with or without Tri-Bi maximal mixing
G. K. Leontaris, N. D. Vlachos
The solar and baseline neutrino oscillation data suggest bimaximal neutrino mixing among the first two generations, and trimaximal mixing between all three neutrino flavors. It has…
Unification, KK-thresholds and the top Yukawa coupling in F-theory GUTs
G. K. Leontaris, N. D. Tracas, G. Tsamis
In a class of F-theory SU(5) GUTs the low energy chiral mass spectrum is obtained from rank one fermion mass textures with a hierarchical structure organised by U(1) symmetries emb…
