Strongly coupled Higgs sector

The Higgs sector of the Glashow-Salam-Weinberg theory of electroweak interactions (referred to form now on as SM) stands out as a sore point in an otherwise elegant theory. Although at low energies, experimental support of the SM is remarkable, no clue has so far been forthcoming to symmetry breaking mechanism of the SM. Nor has there been any experimental clue to the mass (or equivalently the coupling) of the Higgs particle which theoretically is a free parameter of the theory. One can of course hope that the Higgs particle would sooner or later be experimentally found and the SM would indeed be a fundamental description of electroweak forces. However, irrespective of whether the Higgs is found or not, there are theoretical complications. In the paper, the authors discuss some recent investigations by a number of groups and authors concerning the possibility of a strongly coupled Higgs sector. These have become important, since as we will see that irrespective of whether the Higgs is directly seen or not, clear signatures can be predicted that are within the observational limits of the proposed SSC
