PLOT-0006 Sin2beta Plots For Summer 2002 Conferences
Doc Type Public Plots or Figures
Record Created February 16, 2002
Comments These plots support the "Measurement of the CP-violating asymmetry amplitude sin2beta" reported in hep-ex/0207042, which was submitted to PRL in July 2002. The result is sin2beta = 0.741+-0.067+-0.033 and |Lambda| = 0.948+-0.051+-0.017.

This page contains the official plots for the winter 2002 sin2beta result for B decays to charmonium (except etac).  The plots are
  • Flavor tagged deltat and raw CP asymmetry distributions
  • Mes plots for the various decay modes (DeltaE for JpsiKl)
  • Plots showing sin2beta by decay mode and various subsamples.
The analysis is documented in the following BAD notes
  • BAD 356 : General sin2beta analysis documentation (systematic errors, cross checks, etc...)
  • BAD 358 : Details specific to the JpsiKl mode
  • BAD 365 : Conference preprint.
The working area for these plots is
/nfs/farm/babar/AWG/sin2b/data_run2_winter02/plots/kumacs/presentations

Here are some related plot pages

  • PLOT-0008 : CP asymmetry in D*D(*) decays
  • PLOT-0011 : sin2beta measurement in etacKs.
