Beautified with Goodly Shape: Rethinking the Properties of Large Extra Dimensions

Much recent attention has focused on theories with large extra compactified dimensions. However, while the phenomenological implications of the volume moduli associated with such compactifications are well understood, relatively little attention has been devoted to the shape moduli. In this talk, I demonstrate that non-trivial shape moduli can lead to a number of effects which are relevant not only for experimental searches for extra dimensions, but also for the interpretation of experimental data if such extra dimensions are found. This talk reports on work done partly in collaboration with Arash Mafi.
