Presentation Transcript

  1. GLW + ADS Y. Horii and K. Trabelsi • GLW: BDK, DCP eigenstates • ADS: BDK, DKp HFAG inputs exist for rD and dD. Similar observables for BD*K. Additional parameters are onlyr*B and d*B (large gain expected). GLW and ADS observables can be combined to obtainf3 (and rB, dB). Expected sensitivity is 15-20°. Aim to obtain a result this summer.

  5. Y. Horii Status for ADS Belle: DK (772M BB, submitted to PRL) BaBar: DK+D*K (467M BB), DK* (379M BB), D(Kpp0)K (226M BB) CDF: DK (5 fb-1) D*K ADS will provide additional information for f3. Will analyze D*K ADS for this summer. (Expected yield ~20 events.)

  6. Y. Horii Calibration modes for D*K ADS are well reconstructed (Exp.7-65, Case A). D*(Dp0)p D*(Dp0)K BR(D*K)/BR(D*p) = 0.079 ± 0.006 Dh Dp D*(Dg)p D*(Dg)K BR(D*K)/BR(D*p) = 0.081 ± 0.009 Dh Dp PDG D*K/D*p = 0.080 ± 0.007 Will use case-B samples. Will include a qq suppression using NeuroBayes (2-D fit on DE and NB). Hopefully apply simultaneous fit to DK and D*K.

  7. GLW + ADS +GGSZ Y. Horii + K. Trabelsiwith A. Poluektov (?) An improved measurement of f3 can be obtained from “GLW + ADS +GGSZ.” Observables for GGSZ: ±stat ±syst ±syst(model independent) Since x± and y± are functions of f3, rB, and dB (same as GLW and ADS),we can combine the observables for GLW, ADS, andGGSZ. The correlations for x± and y± can be handled by using experimental likelihoods. Expected sensitivity ~ 10°.
