Abstract
We report a measurement of the time-dependent ratio of D0→K π to D0→Kπ decay rates in D*-tagged events using 1.0 fb1 of integrated luminosity recorded by the LHCb experiment. We measure the mixing parameters x′2=(-0.9±1.3)×104, y′=(7.2±2.4)×103, and the ratio of doubly-Cabibbo-suppressed to Cabibbo-favored decay rates R=(3. 52±0.15)×103, where the uncertainties include statistical and systematic sources. The result excludes the no-mixing hypothesis with a probability corresponding to 9.1 standard deviations and represents the first observation of D0-D0 oscillations from a single measurement. © 2013 CERN.
