Summary
An analysis is made of Eegge poles in weak reactions involving two spin-half fermions and two spin-zero bosons, with particular reference to neutrino reactions on spinless targets and meson production in neutrino-electron collisions. The Regge-Khuri representation is used for obtaining the equations for the latter process; a method of solving for the amplitude is outlined. Numerical results are obtained in an effective-range approximation. The form factors governing the high-energy behaviour of peripheral neutrino reactions are evaluated. Some of the difficulties that arise in anS-matrix approach to weak interactions are discussed.
Riassunto
Si analizzano i poli di Regge nelle reazioni deboli che coinvolgono due fermioni di spin 1/2 e due bosoni di spin 0, con particolare attenzione alle reazioni neutriniche su bersagli senza spin e produzione di mesoni in collisioni neutrino-elettrone. Per ottenere le equazioni di quest’ultimo processo si usa la rappresentazione di Regge-Khuri; si delinea un metodo di soluzione per le ampiezze. Si ottengono risultati numerici nell’approssimazione della portata effettiva. Si valutano i fattori di forma che regolano il comportamento alle alte nergie delle reazioni neutriniche periferiche. Si discutono alcune difficoltà che insorgono in un aecostamento tramite la matriceS alle interazioni deboli.
