在这封信中，我们打算用D→VV衰变模式来研究D介子中的CP破坏问题，其中T破坏了三重积关联。这无疑是超越标准模型的新物理学的又一次极好的探索。对于中性点D，我们专注于直接CP破坏，而不考虑D0-D‘0振荡。在实验上，通过全角分析可以获得这种违反CP的信号，特别值得一提的是，即将在北京BES-III上进行的大型D数据样本将提供一个很好的执行它的机会。
In this Letter, we intend to study the problem of CP violation in D meson by D→VV decay mode in which the T violating triple-product correlation is examined. That would undoubtedly be another excellent probe of New Physics beyond Standard Model. For the neutral D, we focus on direct CP violation without considering D0–D¯0oscillation. Experimentally, by a full angular analysis one may obtain such CP violating signals, and particularly it is worth mentioning that the upcoming large D data samples at BES-III in Beijing will provide a great opportunity to perform it.
