Measurement of $y_{CP}$ in $D^0$ meson decays to the $K_S^0K^+K^-$ final state

We present a measurement of the $D^{0}$ - $\overline{D}^{0}$ mixing parameter $y_{C P}$ using a flavor-untagged sample of $D^{0} \to K_{S}^{0} K^{+} K^{-}$ decays. The measurement is based on a 673 fb $^{- 1}$ data sample recorded with the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider. Using a method based on measuring the mean decay time for different $K^{+} K^{-}$ invariant mass intervals, we find $y_{CP} = (+0.11\pm 0.61 ({\rm stat.})\pm 0.52 (\rm syst.))%$.
