SUMMARY:Maurizio Piai (Swansea University)
DESCRIPTION:Large Mass Hierarchies in Strongly-Coupled Dynamics.\nWe study lattice data on non-Abelian gauge theories in the (near-)conformal regime as well as a simple toy model in the context of gauge/gravity dualities. We focus our attention on the ratio R between the mass of the lightest spin-2 and spin-0 resonances\, that for technical reasons is a particularly convenient and clean observable to study. For models in which (non-perturbative) large anomalous dimensions arise dynamically\, we show indications that this mass ratio can be large\, with R > 5. Moreover\, our results suggest that R might be related to universal properties of the IR fixed point.
