Description
We apply a recently developed dilaton-pion effective field theory for
asymptotically free gauge theories near the conformal window to the SU(3)
gauge theory with $N_f=8$ fermions in the fundamental representation.
Numerical data for this theory suggests the existence of a large-mass
regime, where the fermion mass is not small but nevertheless the effective
theory is applicable because of the parametric proximity of the conformal
window. In this regime, we find that the mass dependence of hadronic
quantities is similar to that of a a mass-deformed conformal theory, so
that distinguishing infrared conformality from confinement requires the
study of subleading effects.
