摘要：

The O(alpha(2)m(t)(2)/m(w)(2)) correction to the relation between G(mu) and the vector boson masses is computed in the <(MS)over bar> scheme, and the results are used to investigate the magnitude of the effect on the theoretical prediction of m(w) and sin(2)<(theta)over cap (w)>(m(Z)(2)) from alpha, G(mu), and m(Z).
