Outline of Final Research Achievements

I proposed to study theory of supersymmetry and extra dimensions anticipating their experimental discovery at the time of the start of the LHC experiments. Since then, the Higgs boson was discovered earlier than expected, leading to a major progress establishing the Standard Model, the foundational theory of elementary particles. On the other hand, there are no experimental hints of physics beyond the standard model such as supersymmetry or extra dimensions. Given this dramatic development, major reconsideration of theories of supersymmetry and extra dimensions were warranted. In this proposed research, I proposed new theoretical directions first in the world and studied their experimental verifications by combining the mass of the discovered Higgs boson, lack of direct evidence, and recent data from cosmology and neutrino physics.
