Query: Calculable mass hierarchies and a light dilaton from gravity duals   In the context of gauge/gravity dualities, we calculate the scalar and tensor
mass spectrum of the boundary theory defined by a special 8-scalar sigma-model
in five dimensions, the background solutions of which include the 1-parameter
family dual to the baryonic branch of the Klebanov-Strassler field theory. This
provides an example of a strongly-coupled, multi-scale system that yields a
parametrically light mass for one of the composite scalar particles: the
dilaton. We briefly discuss the implications of these findings towards
identifying a satisfactory solution to both the big and little hierarchy
problems of the electro-weak theory.
