Abstract

The experimental data of the past decade suggests that the quantum gravity vacuum should possess two key ingredients. The existence of three generations and their embedding in SO(10) representations. The Z 2 x Z 2 orbifold of the heterotic string provides examples of vacua that accommodate these properties. The utilization of string dualities to explore these models is discussed. Classification of the Z 2 x Z 2 orbifold with geometric shifts on complex manifolds demonstrates that three generations are not obtained solely with symmetric shifts on complex tori, but necessarily utilize an asymmetric shift or a nonperturbative breaking of the GUT gauge group. The issue of mass and mixing spectrum in the neutrino versus the quark sector is examined.
