摘要:
We examine the problem of constructing three generation free fermionic string models with grand unified gauge groups. We attempt the construction of GxG 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 with an even number of generations. However, for G=SU(5) we find a number of three generation models.
