Abstract: (Springer)
The weak phase γ is conventionally probed by theBs→ρ0 mode. The predicted rate is tiny. Even if aBs→ρ0Ks rate difference could be established, it would not be clear that sin 2γ had been measured, because amplitudes with other weak phases may contribute significantly. Non-CP eigenstates, such asBs→Ds±K∓, have a two-fold advantage overBs→ρ0Ks. Their rates are orders of magnitude above that forBs→ρ0Ks, and they probe theCP-violating phase γ, without any contamination from other weak phases. Detailed time-dependent studies of non-CP eigenstates remove possible final-state phases and extract the weak phase γ.- modeal CP: violation
