We study the phenomenology resulting from backgrounds of the form $AdS_5\times {\cal M}^\delta$, where ${\cal M}^\delta$ denotes a generic manifold ofdimension $\delta \geq 1$, and $AdS_5$ is the slice of 5-dimensional anti-deSitter space which generates the hierarchy in the Randall-Sundrum (RS) model.The $\delta$ additional dimensions may be required when the RS model isembedded into a more fundamental theory. We analyze two classes of$\delta-$dimensional manifolds: flat and curved geometries. In the first case,the additional flat dimensions may accommodate localized fermions which in turncould resolve issues, such as proton decay and flavor, that were not addressedin the original RS proposal. In the latter case, the positive curvature of an$S^\delta$ manifold with $\delta> 1$ can geometrically provide the5-dimensional warping of the RS model. We demonstrate the key features of thesetwo classes of models by presenting the background solutions, the spectra ofthe Kaluza-Klein (KK) gravitons, and their 4-dimensional couplings, for thesample manifolds $S^1/Z_2$, $S^1$, and $S^2$. The resulting phenomenology isdistinct from that of the original RS scenario due to the appearance of amultitude of new KK graviton states at the weak scale with couplings that arepredicted to be measurably non-universal within the KK tower. In addition, inthe case of flat compactifications, fermion localization can result in KKgraviton and gauge field flavor changing interactions.Comment: 30 pages, 8 figures.
