GLW + ADS GLW: B DK, D CP eigenstates ADS: B DK, D K 1 GLW and ADS observables can be combined to obtain 3 (and r B, B ). Expected sensitivity is 15-20°. Aim to obtain a result this summer. HFAG inputs exist for r D and D. Similar observables for B D * K. Additional parameters are only r * B and * B (large gain expected). Y. Horii and K. Trabelsi

PDG D * K/D * = 0.080 ± 0.007 Will use case-B samples. Will include a qq suppression using NeuroBayes (2-D fit on E and NB). Hopefully apply simultaneous fit to DK and D * K. DD DD Dh Y. Horii

GLW + ADS + GGSZ 7 Since x ± and y ± are functions of 3, r B, and B (same as GLW and ADS), we can combine the observables for GLW, ADS, and GGSZ. The correlations for x ± and y ± can be handled by using experimental likelihoods. Expected sensitivity ~ 10°. ±stat ±syst ±syst (model independent) Y. Horii + K. Trabelsi with A. Poluektov (?) An improved measurement of 3 can be obtained from “GLW + ADS + GGSZ.” Observables for GGSZ:
