Outline

In our universe, there are elementary particles: quarks, leptons and vector particles that mediate the strong, the weak, and the electromagnetic forces. Our laboratory studies theoretical aspects of the particle physics. There are a lot of mysteries in our universe and the Standard Model that describes the current experimental results successfully. We do not know, for instance, the origins of the Higgs mass, the fermion mass hierarchy and so on. The dark matter and dark energy problems could be also solved by extension of the Standard Model. We work on those problems, constructing new models based on latest experimental results.
