Description

CP violation in charm meson decays is expected to be small, and an observation of a large CP asymmetry could indicate new physics. We report measurement of branching fractions and CP asymmetries in $D \to K h \pi \pi^{0}$ $(h = \pi, K)$ and T-odd asymmetry, sensitive to CP violation, in the $D^{0} \to K^{0}_{S}K^{0}_{S}\pi^{+}\pi^{-}$ decay, and $D_{(s)}\to KK^{0}_{S}\pi\pi$. The talk also covers other results on charm meson decays. The results are based on the full data collected with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider.
