Value used: Weighted Mean: sin2beta =  0.793 +/- 0.102(stat+syst) Caution:
  • This weighted average uses Gaussian priors for the experimental systematic uncertainties, since the experiments themselves have obtained their final systematic errors from the quadratic sum of the individual contributions.
  • The average does not take into account properly the correction and correlation introduced by the B0 mass difference.
  • Theoretical Parameters
