Description

We present a measurement of the D0-D0 mixing parameter yCP using a flavor-untagged sample of D0→KS0K+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 yCP=(+0.11±0.61(stat.)±0.52(syst.))%.
