Abstract
Using the ARGUS detector at the e{sup +}e{sup -} storage ring DORIS II, measurements of multiplicities of pseudoscalar kaons, of K*(892) and of {phi}(1020) in B meson decays have been performed through studies of angular and charge correlations between the above particles and high momentum leptons produced in semileptonic B decays. The method has made it possible to measure the multiplicities separately for B-mesons and anti-B-mesons. The excess of like charge lepton-kaon pairs over opposite charge pairs in semileptonic decays was used for estimating the ratio of charmed decays over all decays, and thus also the fraction of charmless decays. A search for an excess of fast neutral kaons from rare B decays was also made. All the results obtained support the assumption that almost all B mesons decay through b {yields} c transitions into charmed hadrons. (66 refs.).
