The measurement of the masses m/sub W/ and m/sub Z/ of the weak vector bosons W and Z will provide an accurate determination of the mixing angle theta/sub W/. With this in view, precise theoretical values of sin/sup 2/theta/sub W/, m/sub W/, and m/sub Z/ in the grand unified gauge theory based on SU(5) with three fermion families are given.
