Effect of Weak Interactions on Electromagnetic Properties of Leptons
S. Rai Choudhury, Hamdi Mani · Physical Review · 1969
We have investigated the electromagnetic properties of leptons in the presence of weak interactions, using a model essentially similar to the one recently developed by Gell-Mann, Goldberger, Kroll, and Low. We find that the effect is very small in the anomalous magnetic moment and in the Lamb shift of hydrogen. However, the charge radius of the neutrino turns out to be much larger than the previous estimate of Bernstein and Lee.
