Conformal Symmetry and Single-Meson Production
The results of combining conformal invariance and chiral symmetry are given for the process πN-->ππN. It is shown that if the symmetries are broken spontaneously the data are insufficient to determine the scale of the breaking term. The ππ scattering lengths remain small although both a0 and a2 are altered substantially.
