Abstract
Upper bounds are derived for the mixing between light and heavy gauge bosons in terms of the closeness of the observed W or Z mass to the SU(2)×U(1) prediction m0. The mixing angles between light and heavy bosons with masses m1 and m2, respectively, are less than [(m02-m12)(m22-m02)]12. Existing data imply a limit of 0.04 for the mixing angle between the W and a 1-TeV heavy boson. A similar result holds for the Z if there are no Higgs multiplets with I>12 with significant vacuum expectation values.
