| Research Abstract |
In the international collaboration of the ATLAS experiment, which is running at the world highest energy proton-proton collider at CERN, our research group made essential contributions towards discoveries of Higgs Boson and Supersymmetry. Namely, physicists and engineers in our group contribited to construct the muon-trigger chambers, silicon tracking devise, superconducting solenoid magnet, and the regional data analysis system based on the GRID technology. The mass limit of supersymmetric gluinos and squarks are already exceeding around 800 GeV, and the Higgs Boson is driven into a small mass range. We expect discoveries of these particles in the near future.
The MEG experiment at PSI is searching for a positively charged muon rare decay into positron and gamma. The physicists in our research group proposed the experiment, designed and constructed the major part of the state-of-the-art detector including a liquid Xe calorimeter for gamma, a special superconducting solenoid magnet and very thin drift chambers for positron. Since 2008 the experiment is taking data and the world record upper limit of the muon decay branching fraction into positron+gamma has been established. The theoretical colleagues in our research group made vast contributions in the wide research field from superstring to Higgs/SUSY phenomenology. Also they produced many publications by collaborating with the ATLAS and MEG experimentalists.
