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

Abstract

We present a measurement of the $D^0$-$\overline{D}{}^0$ mixing parameter $y_{CP}$ 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 $y_{CP}=(+0.11\pm 0.61(stat.)\pm 0.52(syst.))$.
