| Outline of Final Research Achievements |
We have studied high energy critical phenomena associated with spontaneous symmetry breaking based on thermal quantum field theory.
As a fundamental theory for spontaneous symmetry breaking, we have constructed a field theory around oscillating solutions of the equation of motion for the Higgs potential. A procedure to suppress the gauge dependence has been proposed in the analysis of Schwinger-Dyson equation for strong coupling QED. We have also evaluated cosmic microwave background fluctuations induced by the primordial inflation. For a fundamental scalar inflaton field, it is found that the two-loop correction on the fluctuations is much larger than the leading-log correction. Introducing a composite scalar inflaton constructed by fermion and anti-fermion, we have proposed the gauged Nambu-Jona-Lasinio inflation model. It is found that the model represents an attractor which can not be found in a fundamental scalar model.
