| Outline of Final Research Achievements |
Although the Higgs particle responsible for the origin of mass has been discovered, its dynamical origin still remains mysterious. This project showed, based on the ladder approximation and also the holographic model, that the discovered Higgs particle is consistent with the composite particle “Technidilaton”predicted by the “Walking Technicolor.
We further made the first-principle calculations of lattice QCD simulations and found that flavor 8 QCD is a candidate for the Walking Technicolor, the result later confirmed by other groups. We also discovered light flavor-singlet scalar meson for flavor-12 (later confirmed by several other groups), and also for flavor-8, the latter being a candidate for the technidilaton to be identified with the discovered Higgs particle as a composite.
