Outline of Final Research Achievements

The walking technicolor was studied based on the ladder approximation and holography, which showed that the technidilaton as a composite Higgs particle can be identified with the Higgs particle discovered at the LHC. Other composite particles such as Technipion, Technirho, predicted in this theory were also studied as to be tested at the upcoming LHC experiments starting in 2015. The lattice SU(3) gauge theory with 8 flavors was also studied by the computer simulations and found to be a candidate for the walking technicolor and for the first time in the world was discovered to have a light composite scalar meson as a candidate for the technidilaton.
