Description

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 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 ± 8stat(-5+30)syst] MeV/c2 and width [239 ± 35stat(-42+46)syst] MeV/c2. (author)
