| Research Abstract |
We have made a comprehensive investigation on various structures of matters in the strong interactions with lattice QCD simulations. What we have achieved are as follows: (i) development of 1+1+1 flavor lattice QCD+QED simulation with the electro-magnetic interactions and the u-d quark mass difference, (ii) measurement of the resonance energy and the decay width of theρ(770) meson state based on the scattering phase shift, (iii) direct construction of the nuclei with atomic mass number A≦4 and calculation of their binding energies, (iv) analysis of the phase structure of QCD at the finite temperature and finite density employing the finite size scaling method.
