Abstract

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