Abstract

We have searched for CP violation of charmed mesons in the decays D→ K⁰_S P, where D denotes D⁰ and D⁺_(s), and P denotes the pseudo-scalar mesons π⁺, K⁺, π⁰, η, and η'. No evidence of CP violation in these decays is observed. We also have measured the CP asymmetry difference between the Cabibbo suppressed decay D⁺→ϕπ⁺ and the Cabibbo favored D⁺_s→ϕπ⁺ decays in the region of |M(K⁺K^-)-M^ϕ_PDG|
