Description

We report an improved measurement of D^0-D^0bar mixing using the time dependence of the Dalitz plot of the decay mode D^0->K_S^0 pi^+ pi^-. In addition, we report results of searches for CP violation in the decays D^0->K_S^0 P^0 where P0 denotes a neutral pseudo-scalar meson which is either a pi^0, eta or eta^'. The result for D^0->K_S pi^0 is the most sensitive search for CP violation in the D^0 system to date. These results are based on a large data sample collected by the Belle detector at the KEKB asymmetric energy electron positron collider.
