However, soon after the ADD model was first studied, it was realised that, in the absence of a mechanism that will stabilise the large radii of compactification, the large disparity between the radii of compactification and the four-dimensional Planck radius shows up as a residual hierarchy. This was historically the main motivation to look for models without large extra dimensions and it was this search that led to the development of the warped extra-dimensional model of Randall and Sundrum [26]. In the meantime, however, a study of Calabi-Yau flux compactifications in Type II B string theory with all moduli stabilised has shown how stable, large-volume compactifications naturally arise in this context. While it seems difficult to generate millimetresized extra dimensions in this scenario, it is easily possible to generate a whole range of large compactification radii and also have physics related to a variety of scales from the Planck scale to the TeV scale [192, 193, 194].Read More
