Electric Dipole Moments of Dyon and `Electron'
Abstract
The electric and magnetic dipole moments of dyon fermions are calculated within N = 2 supersymmetric YangMills theory including the θterm. It is found, in particular, that the gyroelectric ratio deviates from the canonical value of 2 for the monopole fermion (n_{m} = 1, n_{e} = 0) in the case θ ≠ 0. Then, applying the Sduality transformation to the result for the dyon fermions, we obtain an explicit prediction for the electric dipole moment (EDM) of the charged fermion (`electron'). It is thus seen that the approach presented here provides a novel method for computing the EDM induced by the θterm.
