| Outline of Final Research Achievements |
We have performed high-energy proton-proton collision experiment at the Large Hadron Collider(LHC) at CERN and discovered a new particle with the mass around 125 GeV. With careful measurements for its mass, production cross section and branching ratios, we have found that the particle is consistent with the long-sought Higgs particle which the Standard Model(SM) of the particle physics has been predicted. Given its measured mass value and the fact that no other new particles emerged, our results give a significant constraint on building a theory beyond the SM.
In parallel to the Higgs analysis, we have developed radiation-hard pixel detector at the future experiment for the further precision measurements. The basic R&D for the pixel detector has been completed. We have identified radiation-weak location in the device and improved the layout.
