Outline of Final Research Achievements |
What is the origin of elementary particle masses? Higgs boson is the particle predicted in the Standard Model to have spin-0. Its interactions cannot be determined by the gauge principle. On the other hand, the Higgs interactions play important roles to keep the unitarity of the longitudinal gauge boson scattering amplitudes and the renormalizability of the theory. If the measured values of the Higgs couplings would turn out to deviate from the Standard Model predictions, we need to introduce new physics to keep the unitarity and the renormalizability. We discussed this possibility using model independent framework. These results were reported in refereed journal papers and at international conferences.
