Abstract

We reconsider the low-energy effective theory for Higgs-less electroweak symmetry breaking: we study the anomaly-matching in the situation where all Goldstone fields disappear from the spectrum as a result of the Higgs mechanism. We find that the global SU (2)L × SU (2)R ×U(1)B−L symmetry of the underlying theory, which is spontaneously broken to SU(2)L+R… (More)
