| Research Abstract |
We have non-perturbatively computed the neutron electric dipole moment (EDM) from lattice QCD. In the first principle of QCD, we obtain the precise estimate of neutron EDM, which includes the hadronic contribution. On the gauge configuration including dynamical quark effect and CP violation in QCD action, we first show the lattice result of neutron EDM and analysis of quark mass dependence.
