Abstract
We consider various integrated lepton charge-energy asymmetries and az imuthal asymmetries as tests of CP violation in the process e-e+ --> W -W+. These asymmetries are sensitive to different linear combinations of the CP-violating form factors in the three gauge boson W-W+ product ion vertex, and can distinguish dispersive and absorptive parts of the form factors. It makes use of purely hadronic and purely leptonic mod es of W decays as well as the mixed modes. The techniques of using the kinematics of jets or missing momentum to construct CP-odd observable s are also employed. These CP-violating observables are illustrated in the generalized left-right model and the charged Higgs boson model.
