Calculation of Nucleon Electric Dipole Moments Induced by Quark Chromo-Electric Dipole Moments
Published 31 Jan 2017 in hep-lat | (1702.00052v1)
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 $m_\pi=172\text{ MeV}$, we calculate the connected part of the electric dipole form factor $F_3(Q2)$. 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.
