摘要We systematically investigate the possibility of finding CP or T violation in the tau sector at the tau-charm factory. CP or T violation may occur in the tau pair production process, expressed as an electric dipole moment, and in tau decay processes. By assuming that an electric dipole moment as large as 10(-19) e cm and CP or T violation effects originating from tau decay as large as 10(-3) are observable at the tau-charm factory, we study all the possible extensions of the SM which are relevant for generating CP or T violation in the tau sector. And we point out, there are a few kinds of models which are hopeful candidates for generating such CP or T violation. For these models we consider all the theoretical and current experimental constraints and find that there exists some parameter space which will result in a measurable CP or T violation. Therefore we conclude that the tau-charm factory is a hopeful place to discover CP or T violation in the tau sector.
