One of the cornerstones of particle physics in the early 1960's was a phenomeno logically successful theory of weak interactions based on Fermi's original idea [1] of a direct interaction of four spin-½ fields. A decisive role in formulating this theory can be attributed to Feynman and Gell-Mann [2]; an important improvement of the Feynman – Gell-Mann theory is due to Cabibbo [3]…
