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 for any fermion field leads to a unique form of the four- fermion interaction responsible for weak processes. The Hamiltonian contains equal amounts of V and Ar, and is necessarily invariant under time reversal but non-invariant under parity regardless of whether or not the neutrino field is involved. (The results are identical to those obtained by Feynman and Gell-Mann and by Sudarshan and Marshak using somewhat different approaches.) The possible existence of an intermediate charged boson field responsible for all weak processes is discussed with reference to several weak processes which have not been observed. Most experiments in BETA decay and the pi - mu -e sequence are consistent with the predictions of the theory with the important exception of the He/sup 6/ recoil experiment. Various implications of the theory which can be experimentally tested are examined with special attention to the decay interactions of hyperons and K mesons. (auth)
