Probing CP violation in exclusive b -> stiti over line transitions

We consider the time-dependent analysis of rare Bd and Bs decays mediated by b -s nu nu over bar transitions. The inclusion of time evolution allows us to construct novel observables with specific sensitivity to CP-odd phases in these processes. The sensitivity to CP violation of corresponding time-integrated measurements in the presence of flavor tagging is also explored. We provide precise predictions for these observables in the Standard Model and explore their sensitivity to new CP-violating new physics contributions at present and planned future B-physics experiments. As such, these observables provide unique probes of CP violation in b -s nu nu over bar transitions.
