  In this paper we relate the parity-odd part of two and three point
correlation functions in theories with exactly conserved or weakly broken
higher spin symmetries to the parity-even part which can be computed from free
theories. We also comment on higher point functions.
  The well known connection of CFT correlation functions with de-Sitter
amplitudes in one higher dimension implies a relation between parity-even and
parity-odd amplitudes calculated using non-minimal interactions such as
${\mathcal W}^3$ and ${\mathcal W}^2 {\widetilde {\mathcal W}}$. In the
flat-space limit this implies a relation between parity-even and parity-odd
parts of flat-space scattering amplitudes.
