Abstract

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 f_if_j → W^±V(V = γ or Z⁰), where f_i and f_j are elementary fermions. We show that, for example, for the initial state eν̄_e, 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.
