D0D0 mixing and other recent charm results from BABAR

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

D0D0 mixing and other recent charm results from BABAR

  • University of Cincinnati, Department of Physics, Mail Location 0011, Cincinnati, OH 45221-0011, USA

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