Abstract

The formulae for D⁰-D⁰ or B⁰-B⁰ mixing and CP violation at the τ-charm or B-meson factories are derived, for the case that only the decay-time distribution of one D or B meson is to be measured. In particular, we point out a new possibility to determine the D⁰-D⁰ mixing rate in semileptonic D decays at the Ψ(4.14) resonance; and show that both direct and indirect CP asymmetries can be measured at the Υ(4S) resonance without ordering the decay times of two B_d mesons or measuring their difference.
