Breaking E₆ via trinification in F‐theory

Abstract

We consider E 6 GUT model in F-theory approach where E 6 is broken via trinification to the Standard Model (SM) gauge group using non-abelian fluxes. Including the gauge singlet wave function we found hierarchically small values for both the μ term as well as Dirac neutrino masses.

Gauge coupling unification with extra Higgs doublets

“…) and(32) should be replaced by 2N D . The nontrivial extension of the Standard Model is the model with N H = 8, N D = 0 in which there are eight Higgs doublets and no E 6 exotic fields D ⊕ D. In this model, eqs.…”
