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 undoubtedly a sign of New Physics.  We
present the analysis of $CP$-asymmetries of singly Cabibbo-suppressed
decays $D^+ \to \pi^+\pi^0$, using the final dataset
collected by BaBar. We discuss the sensitivity to $CP$-violating phases,
and the correspondent New Physics constraints.
