# N-ification of forces: a holographic perspective on D-brane model building

@article{Franco2008NificationOF, title={N-ification of forces: a holographic perspective on D-brane model building}, author={Sebasti'an Franco and Diego Rodŕıguez-G{\'o}mez and Herman L. Verlinde}, journal={Journal of High Energy Physics}, year={2008}, volume={2009}, pages={030-030} }

We study geometric aspects of extensions of the supersymmetric standard model that exhibit a periodic duality cascade. Via the holographic correspondence, the growth of the gauge group rank towards the UV is interpreted as a gradual decompactification transition. We show that this class of models typically develop a duality wall in the UV, and present an efficient method for estimating the hierarchy between the on-set of the cascade and the formation of the wall. As an illustrative example, we…
