Research Interests

We perform calculation of physical observables in flavor physics using the supercomputers. The physics codes are made based on lattice gauge theory. The results are compared with those of experiments. This leads to a critical test on the validity of the Standard Model.
The major research topics are
1. Lattice gauge theory
2. CP violation in neutral Kaons
3. Semileptonic form factors of B mesons
4. R(D) and R(D^*)
5. Standard Model Phenomenology
6. Flavor Physics
7. Computational Physics
