Abstract

Mixing and CP-violation effects in tagged beams of neutral B mesons are studied. Various oscillations of the yield of decay products are discussed. One type is related to B/sup 0/bold-arrow-left-rightB-bar/sup 0/ transitions and another to CP violation in the decay. B/sup 0//sub s/ mesons are the most promising for the observation of such effects. In the standard model, exclusive decays of B/sup 0//sub s/ mesons related to the transition b..-->..uu-bard are the best for the observation of CP violation in B mesons. Departures from the standard model leading to modification of the mixing and CP-violation parameters are also discussed.
