Description
We present a new analysis that measures CP-violating asymmetries in D*-tagged D^0-->pi^+pi^- decays, where any enhancement from the standard model prediction (of the order of 10^-3) would be unambiguous evidence for New Physics.
A technique combining asymmetries of pi^+pi^-, and K^-pi^+ D^0 decays highly suppresses systematic uncertainties due to detector charge-asymmetric efficiencies allowing a measurement limited only by statistical uncertainties.
In addition, we report an updated measurement of D0-D0bar mixing based on the time-dependent ratio of the decay rates for D^0 --> K^+pi^- and D^0 -->K^-pi^+. Both measurements are based on a sample corresponding to an integrated luminosity of 5.2 fb^-1.
