CP Violation Beyond the Standard Model and Tau Pair Production in e^+ e^- Collisions
read the original abstract
We show that the CP-violating dipole form factors of the tau lepton can be of the order of $\alpha/\pi$ in units of the length scale set by the inverse $Z$ boson mass. We propose a few observables which are sensitive to these form factors at LEP2 and higher e^+e^- collision energies.
