 The preferred way of preventing the formula_5 term from being generated is to introduce an approximate symmetry which acts upon the Higgs sector.In addition to the gauged SU(2)W which acts exactly upon the Higgs doublets, we will also introduce another approximate global SU(2)R symmetry which also acts upon the Higgs doublet.The Higgs doublet is now a real representation (2,2) of SU(2)L × SU(2)R with four real components.
