Scientific paper

We present new measurements of branching ratios and CP violation of neutral and charged charmed mesons with the CDF II detector at Fermilab. Exploiting the high mass resolution of the CDF tracking system, the Cabibbo-suppressed decays D° → K+ K-, D° → π+π- and D± → π∓π±π± are well separated from the much larger Cabibbo-favored decays, even without explicit particle identification, and their branching ratios have been measured with high precision. Accurate understanding of the tracking asymmetries allow us to search for direct CP violation in these decays by looking for an asymmetry in the decay rate of C = 1 and C = -1 mesons.
