Three - Family Grand Unification in String Theory ∗ †
The outstanding question of string theory is whether it describes our universe. This question turns out to be very difficult to answer as the space of classical string vacua has a very large degeneracy, and there lack objective criteria that would select a particular string vacuum among the numerous possibilities. One might expect non-perturbative string dynamics to lift, partially or completel...
متن کاملLocal Grand Unification and String Theory
The low energy effective action of string theory depends strongly on the process of compactification and the localization of fields in extra dimensions. Explicit string constructions towards the minimal supersymmetric standard model (MSSM) reveal interesting results leading to the concept of local grand unification. Properties of the MSSM indicate that we might live at a special location close ...
متن کاملString Models for Locally Supersymmetric Grand Unification
Phenomenologically viable string vacua may require incorporating KacMoody algebras at level ≥ 2. We exploit the free fermionic formulation to construct N=(0,2) world-sheet supersymmetric string models with specific phenomenological input: N=1 spacetime supersymmetry, three generations of chiral fermions in gauge groups SO(10) or SU(5), adjoint Higgses, and a single Yukawa coupling of a fundamen...
متن کاملGrand unification with three generations in free fermionic string models.
We examine the problem of constructing three generation free fermionic string models with grand unified gauge groups. We attempt the construction of G × G models, where G is a grand unified group realized at level 1. This structure allows those Higgs representations to appear which are necessary to break the symmetry down to the standard model gauge group. For G = SO(10), we find only models wi...
متن کاملThree-Family SO(10) Grand Unification in String Theory.
The construction of a supersymmetric SO(10) grand unification with 5 lefthanded and 2 right-handed families in the four-dimensional heterotic string theory is presented. The model has one SO(10) adjoint Higgs field. The SO(10) current algebra is realized at level 3.
