Multiple hierarchies from a warped extra dimension

Theories beyond the Standard Model often contain mass scales hierarchically different from electroweak scale and Planck scale. It has been shown that such hierarchical can be realized as typical energy of multiple 3-branes in a 5D warped spacetime. We present mechanism for stabilizing intervals between extra dimension, by introducing single scalar field with brane-localized potentials. discuss radion stabilization solving Einstein equation motion so backreaction effect on geometry due to presence is taken into account. Perturbations background configuration are then considered proper identification degrees freedom. By their equations motion, we compute spectrum radion-scalar system couplings matter fields, which found suppressed profiles at branes. also Kaluza-Klein gravitons dimension. Some applications setup briefly described. Our analysis provides solid ground build dimension models 3-branes.
