On the analyticity of partial wave amplitudes for unstable particles in perturbation theory

  • A. W. Hendry
Article

Summary

Two-particle scattering processes with one outgoing particle unstable are investigated. The singularities of the physical scattering amplitude and the corresponding partial wave amplitudes are obtained.

Riassunto

Si esaminano i processi di scattering a due particelle, in cui una delle particelle è instabile. Si ottengono le singolarità dell’ampiezza di scattering fisica e le corrispondenti ampiezze dell’onda parziale.
