Froissart bounds with any spin

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

For elastic scattering of particles of arbitrary spin, an invariant amplitude is constructed which has the «positivity» required for Martin's proof of Froissart bounds.

Riassunto

Per lo scattering elastico di particelle di spin arbitrario, si costruisce un'ampiezza invariante che ha la «positività» richiesta per la prova di Martin dei vincoli di Froissart.
