Description

We present an updated measurement of the mixing parameter $y_{CP}$ in the decays $D^0 \to K^+ K^-$ and $D^0 \to \pi^+ \pi^-$. The results are obtained from the full data set of 1 ab${}^{-1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. We report a measurement of $D^0 - \bar D^0$ mixing in $D^0 \to K^0_S \pi^+ \pi^-$ decays using a time-dependent Dalitz plot analysis. The results are obtained from a large data sample collected on the $\Upsilon(4S)$ and $\Upsilon(5S)$ resonances with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider.
