Search for CP violation in $D^0 \to K^+K^-,\pi^+\pi^-$ and $D^0 \to \pi^0\pi^0$

Abstract

We report updated measurements of indirect and direct CP asymmetry in decays $D^0 \to K^+K^-,\pi^+\pi^-$ and a new measurement of direct and indirect CP asymmetry in decays $D^0 \to \pi^0\pi^0$, using the full data sample of the Belle experiment.
