Calculation of Nucleon Electric Dipole Moments Induced by Quark Chromo-Electric Dipole Moments
Abstract
We present initial results of computing nucleon electric dipole moment induced by quark chromo-EDM, CP-violating quark-gluon coupling. Using chirally-symmetric domain wall and M\"obius fermions with pion mass mπ=172 MeV, we calculate the connected part of the electric dipole form factor F3(Q2). In addition, we perform an exploratory study of the method to calculate EDM using uniform background electric field on a lattice introduced without breaking the periodicity in the time direction.
