Abstract

Current HFAG averages of the mixing and CP violation parameters in the D⁰ meson system is to be reviewed. We present recent Belle measurements of the mixing parameters x and y using D⁰→ K⁰_Sπ⁺π^-, and y_CP and A_Γ from D⁰→ h⁺h^-, D⁰→ K^-π⁺, where h denotes K or π. Belle measurements of direct CP violation in D⁺→ K⁰_Sπ⁺, D⁰→ h⁺h^-, and D⁺→ K⁰_SK⁺ decays together with ΔA^hh_CP are to be presented.
