Search for hadronic b→u decays
, Physics Letters B, Vol: 241, Pages: 278-282, ISSN: 0370-2693Using the ARGUS detector at the e<sup>+</sup>e<sup>-</sup> storage ring DORIS II at DESY, we searched for b→u transitions in exclusive hadronic B meson decays. A systematic analysis of B decays into pions has been performed for decay modes with 2-7 pions in the final state. In none of the decays a positive signal was observed. The upper limits obtained on various branching ratios are consistent with the current model predictions. © 1990.

Study of antideuteron production in e+ e- annihilation at 10 GeV centre-of-mass energy
, Physics Letters B, Vol: 236, Pages: 102-108, ISSN: 0370-2693We report a measurement of the production of antideuterons d in e<sup>+</sup>e<sup>-</sup> annihilation at centre-of-mass energies around 10 GeV using the ARGUS detector at the DORIS II storage ring. We observe an enhancement of d production in direct hadronic Υ{hooked}(1S) and Υ{hooked}(2S) resonance decays. From 21 events width a d candidate the inclusive cross section 1 σ<inf>dir</inf><sup>had</sup> · dσ dp and the production rate of antideuterons are determined. A production rate of (6.0±2.0±0.6) × 10<sup>-5</sup> d per direct hadronic Υ{hooked} decay and a 90% CL upper limit of 1.7 × 10<sup>-5</sup> d per e<sup>+</sup>e<sup>-</sup>→qq continuum event are obtained. These results are related to antiproton production through a simple model. © 1990.

Observation of semileptonic charmless B meson decays
, Physics Letters B, Vol: 234, Pages: 409-416, ISSN: 0370-2693A detailed study of the lepton momentum spectrum in υ(4S) decays has been made using the ARGUS detector at the DORIS II e<sup>+</sup>e<sup>-</sup> storage ring at DESY. In the region from 2.3 to 2.6 GeV/c, which is above the endpoint for contributions from B decays via b→c transitions, we observe 41±10 events in excess of known backgrounds. These events are interpreted as a signal for b→u transitions. A model dependent value of 0.10±0.01 is obtained for the ratio of Cabibbo-Kobayashi-Maskawa matrix elements |V<inf>ub</inf>|/|V<inf>cv|</inf>, using the Altarelli et al. model. © 1990.

Measurement of K+K- production in γγ collisions
, Zeitschrift Fur Physik C Particles and Fields, Vol: 48, Pages: 183-190, ISSN: 0170-9739The production of charged kaon pairs in two-photon interactions has been studied with the ARGUS detector and the topological cross section has been measured. The γγ-widths and interference parameters have been determined for the tensor mesons f<inf>2</inf> (1270), a<inf>2</inf> (1318) and f′<inf>2</inf> (1525). The helicity structure assumed for the continuum contribution has a significant effect on the result. Upper limits have been obtained for the γγ-widths of the glueball candidate states f<inf>2</inf> (1720) and X (2230). © 1990 Springer-Verlag.

Exclusive hadronic decays of B mesons
, Zeitschrift Fur Physik C Particles and Fields, Vol: 48, Pages: 543-551, ISSN: 0170-9739Using the ARGUS detector at the e<sup>+</sup>e<sup>-</sup> storage ring DORIS II, we have measured B decays into exclusive final states containing a D or D<sup>*</sup> meson plus several pions, or containing a J/ψ or ψ′ meson plus a strange particle. Some of these channels have not been seen before, while others represent updated measurements of previous results. The branching ratios are compared with the predictions of the model of Bauer, Stech and Wirbel. Using the cleanest decay channels, the mass of the charged and neutral B meson are found to be m<inf>B</inf><sup>-</sup>=(5280.5±1.0±2.0) MeV/c<sup>2</sup> and m<inf>B</inf><sup>0</sup>=(5279.6±0.7±2.0) MeV/c<sup>2</sup> respectively, yielding a mass difference m<inf>B</inf><sup>0</sup>-m<inf>B</inf><sup>-</sup>=(-0.9±1.2±0.5) MeV/c<sup>2</sup>. © 1990 Springer-Verlag.
