Mean Life and Mass of Elementary Particles

Abstract

THE weak interaction constant G may determine the mean life of some elementary particles. If the muon mean life of 2.212 × 10−6 sec is equated to (1/2 πa) (λe3ħ/G) then G equals 1.48 × 10−49 erg cm3 (a is the fine structure constant and λe is the Compton wave-length of the electron). The charged pion mean life equals 1/4 (λeħ/G) or k while the ∑- hyperon mean life equals a k. Three types of particles may exist corresponding to the presence of a with exponents of − 1, 0, or +1 in a function giving the mean life of the particle.
