Outline of Final Research Achievements

This research project aims at clarifying the role to be played by the electron positron linear collider (ILC) for the full elucidation of Tera-scale physics, based on the experimental knowledge from the Large Hadron Collider (LHC), thereby establishing the ILC physics case and strategy for early realization of the ILC. In this research project, it became clear that the three major probes available at the ILC: Higgs, top, and direct search for new particles would provide promising physics potential to advance the knowledge from the LHC to a qualitatively new stage. The results obtained in this research comprise core part of the physics volume of the ILC technical design report and have served as important inputs to formulate the European and the American strategies (Snowmass study), thus made significant contribution to the promotion of the ILC project.
