Abstract

Using the ARGUS detector at the e+e- storage ring DORIS II, flavour-dependent kaon production in B meson decays has been studied. Using the leptons as flavour tags, it has been possible to separately measure the multiplicities of K+, K- and Ks 0 in inclusive B decays and in semileptonic B decays. The kaon production in semileptonic B decays was further used to estimate the ratio of charmed decays over all decays, and thus also the fraction of charmless B decays.
