标题： Search For Non-Standard Model CP/T violation At Tau-Charm Factory

摘要： 我们系统地研究在 Tau-Charm Factory 中找到$\tau$区域中 CP/T 破坏的可能性。 CP/T 破坏可能发生在$\tau$对产生过程中，以电偶极矩形式表示，并且发生在$tau$衰变过程中。 假设电偶极矩大到$10^{-19}$e-cm 以及来自$\tau$衰变的 CP/T 破坏效应大到$10^{-3}$可以在 Tau-Charm Factory 观测到，我们研究了所有与生成$\tau$区域中 CP/T 破坏相关的 SM 的可能扩展。 我们指出存在几种可能生成这种 CP/T 破坏的模型。 对于这些模型，我们考虑了所有理论和当前实验约束，并发现存在一些参数空间会导致可测量的 CP/T 破坏。 因此我们得出结论，Tau-Charm Factory 是一个有望在$\tau$粒子领域发现 CP/T 违反的地方。 显示英文摘要

摘要： We systematically investigate the possibility of finding CP/T violation in the $\tau$ sector at Tau-Charm Factory. CP/T violation may occur at $\tau$ pair production process, expressed as electric dipole moment, and at $tau$ decay processes. By assuming that electric dipole moment as large as $10^{-19}$e-cm and CP/T violation effect orignating from $\tau$ decay as large as $10^{-3}$ are observable at Tau-Charm Factory, we studied all the possible extensions of the SM which are relevent for generating CP/T violation in $\tau$ sector. And we pointed there are a few kind of models, which are hopeful for generating such CP/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/T violation. Therefore we conclude that Tau-Charm Factory is a hopeful place to discover CP/T violation in $\tau$ sector.
