Measurement of D-0-(D)over-bar(0) mixing using the ratio of lifetimes for the decays D-0 -> K-pi(+) and K+K-

We measure the rate of D0-D̄0 mixing with the observable yCP=(τKπ/τKK)-1, where τKK and τKπ are, respectively, the mean lifetimes of CP-even D0→K+K- and CP-mixed D0→K-π+ decays, using a data sample of 384fb-1 collected by the BABAR detector at the SLAC PEP-II asymmetric-energy B Factory. From a samp...
