On the Universality of the Weak Interactions

The universality of weak decay interactions is applied to the introduction of weak interactions using a formal substitution similar to that in the electromagnetic caee. The Latgrangian equation for the no-weak-interaction case is corrected by addition of multipole interaction terms for baryons and bosons and by substitution of universal lepton interaction terms. Thus, the lepton decays of hyperons and beta decays can be described, and almost all the known weak interactions can be derived qualitatively but not quantitatively. (D.L.C.)
