Abstract:
Results of recent searches for new physics in CP violation in charm decays from the BABAR ex-
periment are presented. These results include a measurement of D0 - D0 mixing and searches for
CP violation in two-body D0 decays, a search for CP violation in the charm decays D ! K0
SK
and D s ! K0
SK , K0
S , and a search for direct CP violation in the singly-Cabibbo suppressed
D ! K+K decays. These studies are based on the nal dataset collected by BABAR at the
PEP-II B factory at SLAC in the period 1999-2008. No evidence of CP violation is found in these
charm decays. The measured mixing parameter yCP = [0:72 0:18(stat) 0:12(syst)]% excludes
the no-mixing null hypothesis with a signi cance of 3.3 .
