Non-Gaussianity from Compositeness
  By assuming the field seeding the curvature perturbations $ \zeta $ is a
dynamically arising condensate, we are able to derive the relation $ f_{NL} ^2
\simeq 10^8 H / M_c $ between the non-Gaussianity parameter $ f_{NL} $ and the
ratio of the inflationary scale $ H $ to the cutoff scale $ M_c $ of the
effective theory describing the condensate, thus relating the experimental
bound on $ f_{NL} $ to a bound on $ M_c $.
