Outline of Final Research Achievements

The discovery of the Higgs Boson at LHC made the first target of the ILC project clear, hence the importance of ILC becomes more evident. We showed that precise measurement of Higgs Boson and top quark as well as new particle searches at ILC will find the physics direction beyond the Standard Model. Especially, methods to scrutinize the new physics behind the 750 GeV peak found by the LHC experiments has been developed.
For the development of new detector, the detailed design of the ILC silicon-tungsten electromagnetic calorimeter was performed. The specification of the silicon detector was studies accounting the performance and the cost. Also irradiation test using neutrons was successfully performed at Kobe University, and the calorimeter prototype was successfully tested using the electron beam at DESY.
