  This Master's thesis will introduce the Randall-Sundrum RSI model and
overview its general features and basic phenomenology, with the goal of
understanding its 5-dimensional geometric structure in terms of its
4-dimensional AdS/CFT dual theory. We discuss mode expansions, boundary terms,
field content, and supersymmetry, leading up to a discussion of the AdS/CFT
correspondence in RSI models. Low-energy 4d Yukawa hierarchies and gauge
couplings are understood in terms of the bulk 5d theory. A few simple Standard
Model and MSSM-like constructions are considered, and their 4d dual theories
are discussed. One new result is presented: the 5d bulk interpretation of the
Nelson-Strassler mechanism of generating Yukawa hierarchies through
renormalization group flow.
