Heavy Higgs Bosons
The possibility that weak and electromagnetic interactions are described, in a unified manner, by a spontaneously broken SU(2)L × U(1) gauge theory1 has gained wide experimental support over the past decade. However, one of the least satisfactory aspects of this theory is its reliance on elementary scalar fields to spontaneously break the gauge symmetry and, via the Higgs mechanism, generate masses for the vector bosons.
