{Evidence for D0-D0bar mixing using the CDF II Detector}

Journal Article (Academic article)

We measure the time dependence of the ratio of decay rates for the rare decay D0-->K+pi- to the Cabibbo-favored decay D0-->K-pi+. A signal of 12.7×103 D0-->K+pi- decays was obtained using the Collider Detector at Fermilab II detector at the Fermilab Tevatron with an integrated luminosity of 1.5 fb-1. We measure the D0-[overline D]0 mixing parameters (RD,y[prime],x[prime]2), and find that the data are inconsistent with the no-mixing hypothesis with a probability equivalent to 3.8 Gaussian standard deviations.
