摘要
We present recent results from BABAR experiment for D-0-(D) over bar (0) mixing measurements. Mixing parameters can be measured in different ways using different D-0 decay modes, here we discuss the most sensitive analyses such as D-0 -> K+pi(-) where we had the first evidence of charm mixing, the measurement of the ratio of lifetimes of the decays D-0 -> K+K- and D-0 -> pi(+)pi(-)- relative to D-0 -> K+pi(-), the time dependent Dalitz plot analysis of Do K'nno. New limits on CP-violating time-integrated asymmetries in D-0 -> K+K- and D-0 -> pi(+)pi(-) 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.
