SUMMARY
This fixed-point feature is broken when the new heavy fields decouple at the mass scale M; below this scale, the gauge couplings run independently until they become nonperturbative at the confinement scales ΛQCD and ΛdQCD. The second key assumption is that the couplings run all the way to their IRFP values by the decoupling scale M regardless of the initial coupling values in the UV. While these values of ϵv are not quite as large as those for the best models in Sec VI A, a validity fraction of ~0.3 still corresponds . . .
