Nuclear electric dipole moment of three-body system

Abstract

Nuclear electric dipole moments of ${}^{3}He$ and ${}^{3}H$ are calculated using Time Reversal Invariance Violating (TRIV) potentials based on the meson exchange theory, as well as the ones derived by using pionless and pionful effective field theories, with nuclear wave functions obtained by solving Faddeev equations in configuration space for the complete Hamiltonians comprising both TRIV and realistic strong interactions. The obtained results are compared with the previous calculations of ${}^{3}He$ EDM and with time reversal invariance violating effects in neutron-deuteron scattering.
