| Outline of Final Research Achievements |
One of the most important subjects in elementary particle physics is to search for new physics, which can not be described by the Standard Model, and to construct a new fundamental theory. Flavor physics, namely particle processes associating quark flavor changing, is expected to provide wealth of knowledge about new physics. In this research, we calculate form factors of semileptonic decays in order to improve the accuracy of theoretical prediction on these decays and to promote the search of new physics together with world-wide experimental efforts. It is however difficult to calculate the form factors by conventional analytical methods. We therefore perform numerical simulations of Quantum Chromo-Dynamics on space-time lattices to calculate the form factors of K, D and B mesons. The most salient feature of our research is to achieve a high accuracy by preserving important symmetries of QCD.
