  1. B->D0K GLW plans Outline: Analysis method Reminder Status Future plans Valentina Santoro, Vitaly Eyges

  2. Color suppression CKM suppression 3 unknown rb , d, g Gronau Wyler London method The GLW method can access to g via interference between B+ -> D0K+ D0->f and B+ -> D0K+ D0->f . f is a final states accessible to both D0 and D0 Color allowed b->c transition Color suppressed b->u transition The CP eigenstates accessible to D0 and D0are: CP even: K+K- , p+p- CP odd: Ksp0 , Ksw , Ksf

  3. Reminder Last BaBar analysis published was based on a sample of 232 million Y(4S)->BB decays corresponding to an integrated luminosity of 211fb-1 using the full Run 1-4 dataset They measure: • the partial-rate charge asymmetries ACP± • the ratios RCP± of the B->D0K decay branching fractions • ACP+ = 0.35 ± 0.13(stat) ± 0.04(syst), • ACP− = −0.06 ± 0.13(stat) ± 0.04(syst), • RCP+ = 0.90 ± 0.12(stat) ± 0.04(syst), • RCP− = 0.86 ±0.10(stat) ± 0.05(syst). We are going to update the analysis with Run5 and part of Run6 dataset for next summer

  4. Analysis status The analysis is just started We are using the GLW/ADS skim and ntuples produced last year We are now working on the ntuple reduction
