Abstract
The asymptotic high-energy behavior of the elastic scattering amplitude for two spin-0 particles for fixed angle ϑ (ϑ≠0∘,ϑ≠180∘) is calculated from the condition of conformal invariance. For elastic π0−π0 scattering we obtain for the differential cross section dσdΩ≈(1s)(m2s)F12(cosϑ). The π0 is assigned to an irreducible representation of the conformal group with continuous mass spectrum.
