Description
The status of CP violations in charm sector is still unsettled.
According to SM, the predicted asymmetries are small, but often affected by large uncertainties due to long-distance effects. However, it is possible to build observables which SM predicts to be CP conserving, so that any measured asymmetry is, with no doubts, a sign of New Physics.
We present recent results on charm CP violation at Belle and BaBar. We show the measurement of CP asymmetries in D+ -> K+ K- pi+, D+ -> KS K+, Ds+ -> KS K+, Ds+ -> KS pi+ at BABAR. Moreover, we show the Belle measurements of indirect CP violation parameters from D0 -> KS pi pi decay.
