Muon Magnetic Moment in a Finite Theory of Weak and Electromagnetic Interactions

We calculate the weak-interaction contribution to the muon anomalous magnetic moment of the order $G_{W}m_{\mu }^{}{}_{}{}^2$ in the Weinberg model for leptons. Using a $\xi$-limiting procedure we obtain a finite correction to $\frac{1}{2}\mathrm{}(g-2\mathrm{})\mathrm{}$, which has the value (1.8-2.2) × ${10}^{-9\mathrm{}}$.
