摘要
Using the ARGUS detector at the e+e- storage ring DORIS II at DESY, penguin decays of B mesons involving b --> sX+X-have been searched for, where X is one of e, mu, pi, or K. No evidence for these decays was found and upper limits are quoted. These numbers represent important constraints of flavour-changing neutral currents in B meson decays and probe the heavy-quark and Higgs sectors of the standard model.
