We point out that the flavor problem in theories with dynamical electroweak symmetry breaking can be effectively decoupled if the physics above the TeV scale is strongly conformal, and the electroweak order parameter has a scaling dimension d = 1+ ǫ with ǫ ≃ 1/few. There are many restrictions on small values of ǫ: for ǫ≪ 1, electroweak symmetry breaking requires a finetuning similar to that of the standard model; large-N conformal field theories (including those obtained from the AdS/CFT… Expand
