Nuclear electric dipole moments in chiral effective field theory
Journal of High Energy Physics
We provide a consistent and complete calculation of the electric dipole moments of the deuteron, helion, and triton in the framework of chiral effective field theory. The CP-conserving and CP-violating interactions are treated on equal footing and we consider CP-violating one-, two-, and three-nucleon operators up to next-to-leading-order in the chiral power counting. In particular, we calculate for the first time EDM contributions induced by the CP-violating three-pion operator. We find thatdoi:10.1007/jhep03(2015)104 fatcat:j4rvvhfuunfcffg47u7rfm3j4q
