For the neutron to have an electric dipole moment (EDM), the theory of nature must have T, or equivalently CP, violation. Neutron EDM is a very good probe of novel CP violation in beyond the standard model physics. To leverage the connection between measured neutron EDM and novel mechanism of CP violation, one requires the calculation of matrix elements for CP violating operators, for which lattice QCD provides a first principle method. In this paper, we review the status of recent lattice QCD calculations of the contributions of the QCD Θ-term, the quark EDM term, and the quark chromo-EDM term to the neutron EDM.

Neutron Electric Dipole Moment

We investigate a CP violating observable, the μ-polarization, in η → μ+μ− in several models with the standard gauge group. The CP violating parameters are constrained by the experimental upper bound on the neutron electric dipole moment. Among the models considered here, it was found that those with leptoquark scalars dominate the contributions to μ-polarization in η → μ+μ−. μ-polarization can be of order 10−3.
