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.

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:
