Abstract

A $W$ -boson electric dipole moment $\frac{λ_{W} e}{2 m_{W}}$ can induce fermion electric dipole moments via quantum loop corrections. Updating an analysis by Salzman and Salzman, we estimate this effect and find that the current neutron-electric-dipole-moment bound $| d_{n} | < 6 \times 10^{- 25}$ e cm implies (barring an unforeseen cancellation) $| λ_{W} | < 1 \times 10^{- 3}$ or $| d_{W} | < 10^{- 19}$ e cm. On the basis of this constraint, we conclude that electricdipole-moment contributions to radiative $W$ -boson processes must be very small and effectively undetectable.
