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

Understand

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.
