N2 - We study the possibility of measuring the CP-odd electric and weak-electric dipole moments (edm and wedm, respectively) of the W-boson through an analysis of the helicity amplitudes in the process fifj → W±V(V = γ or Z0), where fi and fj are elementary fermions. We show that, for example, for the initial state eν̄e, such moments can be detected in the angular distribution of the final state pair when their helicities are (0, ±) for V = γ, or (±, 0) and (0, ±) for V = Z0.
