I consider generalizations of the Georgi-Glashow unified gauge theory to SU(n), and show that sin2θW=(n-2) / 2(n-1). I also note a difficulty in extracting the value of sin2θW from neutral-current data, and suggest that the best method for doing so is the comparison of ν̅ μ-e and νμ-e scattering provided that the ratio of the cross sections is less than 13 / 7.
