Abstract：
We present recent results from BABAR experiment for D⁰－D⁰ mixing measurements. Mixing parameters can be measured in different ways using different D⁰ decay modes, here we discuss the most sensitive analyses such as D⁰→K⁺π^－ where we had the first evidence of charm mixing, the measurement of the ratio of lifetimes of the decays D0→K⁺K^－ and D⁰→π⁺π^－ relative to D⁰→K^－π⁺, the time dependent Dalitz plot analysis of D⁰→K⁺π^－π⁰. New limits on CP-violating time-integrated asymmetries in D0→K⁺K^－ and D0→π⁺π^－ are also discussed. The analyses presented are based on 384 fb^－1 data collected with the BABAR detector at the PEP-II asymmetric B Factory.
