Description
In a first part I will deduce scaling dimensions by matching
the chirally broken gauge theory to the pion effective theory.
Consistency with soft theorems, the lattice and N=1 supersymmetric gauge theories will be discussed.
In a second part, I will consider how the interpretation extends to include a dilaton, the Goldstone due to spontaneous scale symmetry breaking. Gravitational form factors offer a way to assess the sigma-meson as a dilaton and infrared conformality. I will confront these signatures with recent lattice data.
