Outline of Final Research Achievements

We have intensively studied the high-scale supersymmetry model (Pure gravity mediation model) form both theoretical and phenomenological viewpoints, which is now known to be one of the most influential models thanks to the discovery of the Higgs boson at the LHC as well as the non-observation of robust new physics signals at various experiments and observations. We have proposed a novel idea to solve the so-called the hierarchy problem concerning the electroweak scale within the framework of the modal and have shown that the indirect detection of the dark matter (predicted in the model) utilizing the gamma-ray observation of dwarf spheroidal galaxies allows us to robustly test the model in near future.
