| Research Abstract |
What is the physics hidden behind the origin of elementary particle masses? The Higgs potential causes the hierarchy problem in the Standard Model and it is therefore theoretically unsatisfactory. We explored the possibility of "Higgsless" theories, achieving the electroweak symmetry breaking without invoking an Higgs scalar particle, in the deconstructed extra dimension framework. It was explicitly demonstrated that such a model can be constructed consistently with the electroweak and flavor precision tests. We also discussed the structure of the longitudinal gauge boson scattering and the collider phenomenology in such a model. These results were reported in refereed jounal papers and at international conferences.
