Description
Recent simulations suggest the existence of a very light singlet scalar
in QCD-like theories that may be lying just outside the conformal window.
Assuming that the lightness of this scalar can be explained by an
approximate dilatation symmetry, we develop an effective field theory
framework for both the pions and this light scalar, the "dilatonic meson."
We argue that a power counting exists that puts this effective field theory
on a systematic footing.
