Abstract and subjects
The connection between a regularization-independent symmetric momentum substraction (RI-\(\tilde{\rm S}\)MOM) and the \(\overline{\rm MS}\) 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.
