Abstract: (Springer)
An attempt is made to construct a theory of all weak processes from a single invariance principle. The requirement that the weak interaction Hamiltonian be invariant under the reversal of the sign of the mass in the Dirac equation separately forany fermion field leads to a unique form of the four-fermion interaction responsible for weak processes. The Hamiltonian contains equal amounts ofV andA, and is necessarily invariant under time reversal but non-invariant under parity regardless of whether or not the neutrino field is involved. (Our results are identical to those obtained byFeynman andGell-Mann and bySudarshan andMarshak using somewhat different approaches.) The possible existence of an intermediatecharged boson field responsible for all weak processes is discussed with reference to several weak processes which have not been observed. Most experiments in β decay and the π-μ-e sequence are consistent with the predictions of our theory with the important exception of the6He recoil experiment. Various implications of our theory which can be experimentally tested are examined with special attention to the decay interactions of hyperons and K-mesons.References(0)
