CP violation and CKM phases from angular distributions for B-s decays into admixtures of CP eigenstates

We investigate the time evolutions of angular distributions for B-s decays into final states that are admixtures of CP-even and CP-odd configurations. A sizable lifetime difference between the B-s mass eigenstates allows a probe of CP violation in time-dependent untagged angular distributions. Interference effects between different final state configurations of B-s-->D-s*D-+(s)*(-), J/psi phi determine the Wolfenstein parameter eta from untagged data samples, or, if one uses \V-ub\/\V-cb\ as additional input, the notoriously difficult to measure CKM angle gamma. Another determination of gamma is possible by using isospin symmetry of strong interactions to relate untagged data samples of B-s-->K*K-+*(-) and B-s-->K*(0) (K) over bar*(0). We note that the untagged angular distribution for B-s-->rho(0) phi provides interesting information about electroweak penguin diagrams.
