Neutron Electric Dipole Moment from quark Chromoelectric Dipole Moment

The connection between a regularization-independent symmetric momentum substraction (RI-$\tilde{\mathrm{S}}$MOM) and the $\overline{\mathrm{M}\mathrm{S}}$ scheme for the quark chromo EDM operators is discussed. A method for evaluating the neutron EDM from quark chromoEDM is described. A preliminary study of the signal in the matrix element using clover quarks on a highly improved staggered quark (HISQ) ensemble is shown.
