Reappraisal of two-loop contributions to the fermion electric dipole moments in R-parity violating supersymmetric models

We reexamine the R-parity violating contribution to the fermion electric and chromo-electric dipole moments in the two-loop diagrams. It is found that the leading Barr-Zee-type two-loop contribution is smaller than the result found in previous works, and that electric dipole moment experimental data provide looser limits on R-parity violating couplings.
