Abstract：
Studies in which BABAR data have shown evidence for mixing in the neutral charm meson system are presented. A new measurement of the lifetime difference parameter y_CP=(1.16±0.22±0.18)% is described. Results are also presented from a systematic study of DK and D^*K invariant mass distributions from a 470 fb^－1 sample of asymmetric e⁺e^－ interactions recorded by the BABAR detector at the PEP-Ⅱ storage rings. A new charmed-strange meson has been observed with mass [3044±8_stat(⁺³⁰_－5)_syst]MeV/c² and width [239±35_stat(⁺⁴⁶_－42)_syst]MeV/c².
