F-theory Compactifications for Supersymmetric GUTs
We construct a family of elliptically fibered Calabi-Yau four-folds Y_4 for
F-theory compactifications that realize SU(5) GUTs in the low-energy limit. The
three-fold base X_3 of these fibrations is almost Fano and satisfies the
topological criteria required to ensure that the U(1)_Y gauge boson remains
massless, while allowing a decoupling of GUT and Planck scale physics. We study
generic features of these models and the ability to engineer three chiral
generations of MSSM matter. Finally, we demonstrate that it is relatively easy
to implement the topological conditions required to reproduce certain
successful features of local F-theory models, such as the emergence of flavor
hierarchies.Comment: 55 pages, 10 figure
