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

  • A. W. Hendry


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.


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.
