We report on the latest searches for D0 - D0 mixing and CP violation in charm decays at the BABAR experiment. We present a measurement of the lifetime ratio parameter yCP in the two-body K- K+ and p-p+ final states that excludes the no mixing hypothesis with a significance of 3.3s . A search for indirect CP violation in the same channels has also been performed. A search for CPV in the D+ ? KS0K+, D+s ? KS0 K+, D+s ? KS0 p+ and D+ ? K+ K- p+ decays is also presented. No indication of CPV in charm decays is found.

Abstract
We report on the latest searches for D0 - D0 mixing and CP violation in charm decays at the BABAR experiment. We present a measurement of the lifetime ratio parameter yCP in the two-body K- K+ and p-p+ final states that excludes the no mixing hypothesis with a significance of 3.3s . A search for indirect CP violation in the same channels has also been performed. A search for CPV in the D+ ? KS0K+, D+s ? KS0 K+, D+s ? KS0 p+ and D+ ? K+ K- p+ decays is also presented. No indication of CPV in charm decays is found.File in questo prodotto:
