Abstract
We demonstrate that time-dependent studies of angular distributions for B s decays caused by b → cu s quark-level transitions extract clearly and model-independently the CKM angle γ. This CKM angle could be cleanly determined from untagged B s decays alone, if the lifetime difference between the B s mass eigenstates B s L and B s H is sizable. The time dependences for the relevant tagged and untagged observables are given both in a general notation and in terms of linear polarization states and should exhibit large CP-violating effects. These observables may furthermore provide insights into the hadronization dynamics of the corresponding exclusive B s decays, thereby allowing tests of the factorization hypothesis.
