## Abstract

We study the sensitivity of a 500 GeV e^{+}e^{-} linear collider to CP violating anomalous couplings. We find that with 50 fb^{-1}, and taking only one non-zero coupling at a time, the process e^{+}e^{-} → W^{+}W^{-} can be used to place the 95% confidence level bounds |κ̃_{γ}|≤0.1, |κ̃_{Z}|≤0.1 and |g^{Z}
_{4}|≤0.1 from CP even observables. By studying certain distributions in the process e^{+}e^{-}→μ^{+}μ^{-}νν̄ one of the bounds can be improved to |g^{Z}
_{4}| ≤0.06. This process also allows the construction of a CP odd observable which can be used to place bounds on CP violating new physics. At the 95% confidence level we find |κ̃_{γ}|≤0.3, |κ̃_{Z}|≤0.2 and a much weaker bound for |g^{Z}
_{4}|.
