Many theories describing physics beyond the Standard Model rely on a large separation of scales. Large scale separation arises in
models with mass-split flavors if the system is conformal in the
ultraviolet but chirally broken in the infrared. Because of the
conformal fixed point, these systems exhibit hyperscaling and a highly
constrained resonance spectrum.

In numerical simulations we investigate the light-light and heavy-heavy spectrum, confirm our expectation on hyperscaling, and find, moreover, that the iso-singlet scalar ($0^{++}$) is "light" and lies below the vector resonance. The spectrum is qualitatively different from QCD and exhibits e.g. quarkonia with masses not proportional to the constituent quark mass. We expect these resonances to be within reach of the LHC.
