An Update on g / 2 Factors
Gordon L. Ziegler
Iris Irene Koch
The traditional use of g-factors of charged leptons is in calculating the precession in their spins. The present authors have another use for them; namely in deriving the masses of elementary particles from first principles. No such derivation is complete without the appropriate g/2-factor for the particle in question. Thus it is appropriate that a paper on g/2-factors accompany a paper deriving the masses of elementary particles. This companion paper presents the advances in the science of g/2-factors since an earlier work published in 2006.
