BESIII上D-> VV衰变CP破坏的研究

Study of CP violation in D->VV decay at BESIII

Xian-Wei Kang, Hai-Bo Li

摘要:

本文用$D\to VV$衰变模式研究了$D$介子的CP破坏问题,其中考察了T破坏的三重积关联.这无疑是对新物理学在标准模型之外的又一次极好的探索。对于中性的$D$,我们只考虑了直接的CP破坏,而没有考虑$D^0-\bar D^0$振荡.在实验上,通过全角度分析,可以获得这样的CP破坏信号,特别值得一提的是,即将到来的大$D$数据样本在北京BES-III将提供一个很好的机会来执行它。

英文摘要:

In this paper, we intend to study the problem of CP violation in $D$ meson by $D\to VV$ 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 $D^0-\bar D^0$ oscillation. 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.
