| Research Abstract |
Lattice QCD calculation of hadron matrix elements was applied to investigate the CP violation. After demonstrating the effectiveness of our relativistic heavy quark action by a numerical test, we started to calculate physical quantities associated with heavy quarks including the polarization effects of up, down, strange quarks. For the neutron electric dipole moments, we compared the results obtained with the external electric method both in the quenched approximation and the two flavor QCD.
