Predicted mass hierarchies for composite states

Initial phenomenological implications outlined

Abstract

Gauge/gravity dualities provide a very useful approach into solving strongly coupled systems. We apply this to Composite Higgs models and determine the mass hierarchies of the corresponding bound states. As a cross check we apply this to QCD and compare the results to existing lattice calculations for which we find good agreement. We then focus on a particular example whose phenomenology has recently been studied in the literature in a generic way and outline first phenomenological implications of our findings for the spectrum.
