A theorem on the elimination of contact muon-electron interactions

Abstract

A general theorem on the elimination of possible contact muon-electron interactions is given which includes as particular cases a theorem by Cabibbo and Gatto and a theorem by Feinberg, Kabir and Weinberg for particular types of interactions. Viene dimostrato un teorema generale che permette l’eliminazione di eventuali interazioni locali μ-e e che contiene come casi particolari un teorema di Cabibbo e Gatto ed un teorema di Feinberg, Kabir e Weinberg.
