摘要：

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 yCP =(1.16±0.22±0.18)% is described.Results are also presented from a systematic study of DK and DK 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 ±8stat(+350)syst]MeV/c2 and width [239± 35stat(-42+46)syst]MeV/c2.
