  We review dilaton chiral perturbation theory (dChPT), the effective
low-energy theory for the light sector of near-conformal, confining theories.
dChPT provides a systematic expansion in both the fermion mass and the distance
to the conformal window. It accounts for the pions and the light scalar, the
approximate Nambu-Goldstone bosons for chiral and scale symmetry, respectively.
A unique feature of dChPT is the existence of a large-mass regime in which the
theory exhibits approximate hyperscaling, while the expansion nevertheless
remains systematic. We discuss applications to lattice data, presenting
successes as well as directions for future work.
