HFAG inputs exist for rD and dD.
Similar observables for BD*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.
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.)
Calibration modes for D*K ADS are well reconstructed (Exp.7-65, Case A).
BR(D*K)/BR(D*p) = 0.079 ± 0.006
= 0.081 ± 0.009
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.

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°.
