Abstract

We calculate the time-dependent and time-integrated decay rates of (D⁰D⁰)→ (K^±π^∓)(l^±X^∓) at the ψ(3.77) and ψ(4.14) resonances. The possibilities to distinguish between the effects of D⁰-D⁰ mixing and doubly Cabibbo suppressed decay (DCSD) are illustrated, and the signal of CP violation induced by the interplay of mixing and DCSD is discussed. Ratios of the decay rates of (D⁰D⁰)→ (K^±π^∓)(K^±π^∓) to that of (D⁰D⁰)→ (K⁺π^-)(K^-π⁺) are also recalculated by accommodating CP violation and final-state interactions.
