| Research Abstract |
The dynamical origin of the electroweak symmetry breaking in the standard theory of elementary particles was investigated from the view point of the composite Higgs models. Major results of our research in the full period of the project read
1. construction of the dynamical model of the CP violation,
2. development of the method of the electroweak precision measurements to test the composite Higgs models,
3. development of a new technique in perturbation theory
4. investigation of the phase structure of the composite models under strong gravity at high temperature and density.
