Summary
The decay modes K → π + charged lepton + ν and Y → N + +charged lepton+ν are studied by dispersion relation methods. The final spectra for K3 decays are derived from the solution of an integral equation for the decay amplitude. The methods of solutions for such equations are briefly reviewed.
Riassunto
I modi di decadimento K → π + leptone carico + ν e Y → N + leptone carico + ν vengono studiati con tecniche di relazione di dispersione. Gli spettri finali per i decadimenti K3 sono ricavati dalla soluzione di una equazione integrale per l’ampiezza di decadimento. I metodi di soluzione per tali equazioni vengono esposti brevemente.
