Charge/Theme of the session:

  1. Please see first the

    General charges for all experimental talks in WG4

  2. In addition, please consider for the experimental talks:

    • How is the CP-even fraction for K+K–Ks determined ?
    • How is the vertex reconstructed in modes with tracks from Ks only ?
    • How is background in ΦKL estimated ?
  3. For the theoretical talks:

    • What are the SM predictions for the deviation from sin2β in all these modes ? That is, what are the methods one can use to calculate them and how these methods can be checked ?
    • Are there other s-penguin decays that one can use ?
    • Can the sign of the deviation be obtained ?
    • Are there correlations between the deviation in these modes ? Are there observables or combinations of observables that have smaller SM uncertainties (sums, ratios etc.) ?
