Observation of inclusive D<inf>S</inf> production in B meson decay
, Physics Letters B, Vol: 187, Pages: 425-430, ISSN: 0370-2693Using the ARGUS detector at the e+ e- storage ring DORIS II, we have observed inclusive DS production, using the channel DS- → φπ-, in decays of B mesons produced on the Υ{hooked}(4S). The product of branching ratios BR(B→DSX)·BR(DS-→φ π-) is (4.2±0.9±0.6) × 10-3. The DS momentum spectrum suggests a substantial two-body component to the final states of B→DSX decays. © 1987.

Reconstruction of B mesons
, Physics Letters B, Vol: 185, Pages: 218-222, ISSN: 0370-2693B mesons have been reconstructed in five decay channels of the type B→D*±nπ(n=1,2,3) using data accumulated by the ARGUS experiment at the e+e- storage ring DORIS II at DESY. In total, we find 40 neutral B mesons above a background of 15±6 events with a mass of (5278.2±1.0±3.0) MeV/c2 and 32 charged B mesons above a background of 17±6 events with a mass of (5275.8±1.3±3.0) MeV/c2. The decays B0D*+π-π0, B0D*+π-π-π+, and B-→D*+π-π-π0 have been observed for the first time. We find substantially smaller branching ratios for the decay modes B0→D*+π- and B-→D*+π-π- than previously published by the CLEO collaboration. © 1987.

Evidence for the decay τ<sup>-</sup>→ν<inf>τ</inf>ωπ<sup>-</sup>
, Physics Letters B, Vol: 185, Pages: 223-227, ISSN: 0370-2693Using the ARGUS detector at DORIS II, we have analyzed tau decays into π-π-π+π0ν τ. The branching ratio was determined to be (4.2±0.5±0.9)%. From a study of the three pion sub-system, we find evidence for the decay τ-→ωπ-ντ with a branching ratio of (1.5±0.3±0.3)%. The ωπ- system is found to be predominantly in a JP=1- state. There is no evidence for second-class axial-vector currents. The spectral function for the ωπ- final state is in agreement with a prediction based on CVC and σe+e-→ωπ0. © 1987.

Search for lepton-number and lepton-flavour violation in tau decays
, Physics Letters B, Vol: 185, Pages: 228-232, ISSN: 0370-2693We have searched for neutrinoless tau decays into three charged particles as evidence for lepton-flavour or lepton-number violation. The data were collected using the ARGUS detector at the DORIS II storage ring. Tau pairs were produced by e+e- annhilation at centre-of-mass energies near 10 GeV. No evidence for lepton-number or lepton-flavour violation was observed, but the upper limits obtained are an order of magnitude lower than those previously published. © 1987.

Observation of octet and decuplet hyperons in e<sup>+</sup>e<sup>-</sup> annihilation at 10 GeV centre-of-mass energy
, Physics Letters B, Vol: 183, Pages: 419-424, ISSN: 0370-2693Results on hyperon production are reported for data accumulated at 10 GeV centre-of-mass energy with the ARGUS detector. Signals for both the octet states Λ, Σ0 and Ξ- and the decuplet states Σ± (1385), Ξ0 (1530) and Ω- are observed 1 (references to a specific state are to be interpreted as also implying the charge conjugate state), some for the first time in e+e- annihilation. Baryon rates from γdir (1S) decays are enhanced by a factor of about 3 over the continuum. © 1987.

The decay {Mathematical expression}
, Zeitschrift für Physik C Particles and Fields, Vol: 33, Pages: 359-362, ISSN: 0170-9739The decay {Mathematical expression} has been investigated using data accumulated by the ARGUS experiment, which operates at around 10 GeV centre-of-mass energies The decay {Mathematical expression} is a signature for flavor annihilation by W-exchange in weak decays. It is shown that this decay occurs at (15.5±3.3)% of the rate for the well established decay {Mathematical expression}π+π-. This translates into a branching ratio for {Mathematical expression} of (1.18±0.25±0.17)% © 1987 Springer-Verlag.

Neutrino mass from the beta spectrum in the decay of tritium
, Physical Review Letters, Vol: 58, Pages: 2019-2022, ISSN: 0031-9007The data from the spectrum measurement of the tritium decay in a valine molecule carried out in a wide energy range (3.4 keV) with the Institute of Theoretical and Experimental Physics spectrometer are analyzed. The combined analysis of both these data and the data of the previous cycle gives the neutrino mass 30.3-8+2 eV. The model-independent mass interval 17<M<40 eV is derived from the mass difference of the doublet H3-He3. © 1987 The American Physical Society.

Search for exotic decay modes of the Υ{hooked}(1S)
, Physics Letters B, Vol: 179, Pages: 403-408, ISSN: 0370-2693A search for two exotic decay modes of the Υ{hooked}(1S) meson has been made using the ARGUS detector at the e+e- storage ring DORIS II at DESY. The first was Υ{hooked}(1S) decays into weakly interacting particles, for which an upper limit of 2.3% at the 90% CL on the branching ratio is found. The second mode was Υ{hooked}(1S)→γa, where a is a neutral particle with mass less than 1.5GeV/c2, that either decays inside the detector or is sufficiently long-lived to escape detection. For short-lived particles a decaying into an e+e- pair, upper limits on the BR(Υ{hooked}(1S)→γa) of 3.1 × 10- at the 90% CL are found. The upper limit without restriction on the lifetime of a is found to be 1.3 × 10-3. Limits for other decay modes are also given. © 1986.
