| Abstract: | Superstring theory is a unique candidate for the unification of all fundamental interactions. As such, superstring theory should reproduce the Standard Model of elementary gauge interactions. In this thesis I study how the Standard Model may be derived from the string by using the free fermionic formulation. I study the construction of string spin structure models. I argue that the most natural number of chiral generations in this construction is only three. I investigate the construction of Standard-like Models and present an explicit example. I explore the phenomenological implications of this class of models. I argue that the requirement of proton stability necessitates the existence of an additional Z' at O(1 - 100)TeV. I demonstrate that the Z - Z ' mixing give possible observable effects at LEP1, a reduction in the invisible width and an enhancement of the partial widths to baryons and charged leptons. The existence of the Z' and cosmological considerations motivates the construction of a see-saw mechanism, the implication of which is a v[r] at O(10MeV -- 10KeV) and could accommodate the Simpson neutrino. I suggest that the lightness of v[e] and relative to v[μ] may be an indication of SO(10) unification. Because of the unification of the top and v[r] Uukawa couplings, the heaviness of the top relative to the lighter quarks is reflected in the lightness of v[e], v[μ] relative to v[r]. |
