A Search for Direct CP Violation in Two-Body Cabibbo-Suppressed Decays of Neutral Charmed Mesons

Creators

Description

Presented are the results of a search for direct CP violation in Cabibbo-suppressed decays of D0 to two charged daughters. The analysis described was performed on ∼230 fb-1 of the BABAR data sample, recorded at the Stanford Linear Accelerator Center and using the PEP-II electron storage rings. We measure CP asymmetries for decay to the KK and ππ final states, as well as for the branching ratio, and develop a new technique for tagging-efficiency correction using the Cabibbo-favored Kπ final state. We find some evidence for CP violation in decays to the KK final state and results that suggest CP violation in the ππ final state as well
