Search for gluinos in decays of the χ<inf>b</inf>(1<sup>3</sup>P<inf>1</inf>) meson
, Physics Letters B, Vol: 167, Pages: 360-364, ISSN: 0370-2693Using the ARGUS detector at the DORIS II e+e- storage ring, we have searched for gluinos (g), the supersymmetric partner of the gluon, by looking for secondary decay vertices in hadronic decays of χb(13P1) mesons. Events containing χb(13P1) states were selected by detecting the radiative transition from the Υ{hooked} (2S) in a data set corresponding to an integrated luminosity of 38.6 pb-1. The absence of secondary vertices from gluino decays into hadrons and a photino allows us to exclude gluinos in a mass range from 1 to 4.5 GeV/c2 and a lifetime range from 10-11 to 10-9 s. © 1986.

Observation of a new charmed meson
, Physical Review Letters, Vol: 56, Pages: 549-552, ISSN: 0031-9007Using the ARGUS detector at the DORIS II e+e- storage ring at DESY, we have obtained evidence for a new charmed resonance which decays into D*(2010). The observed mass and width are 2420 6 MeV/c2 and 70 21 MeV/c2, respectively. The fragmentation function is found to be hard, as expected for a state containing a leading charm quark produced by nonresonant e+e- annihilation. © 1986 The American Physical Society.

Measurement of tau decays into three charged pions
, Zeitschrift für Physik C Particles and Fields, Vol: 33, Pages: 7-12, ISSN: 0170-9739We report a study of the decay τ-→τ-τ+τ-vτ using the ARGUS detector at the DORIS II storage ring. Tau pairs were produced by e+e- annihilation at centre-of-mass energies near 10 GeV. We have observed about 1,700 events, corresponding to a branching ratio for τ-→τ-τ+τ-vτ of (5.6±0.7)%. The dominant mode for this decay is observed to be ρ0π- in a Jp=1+ spin state. The ρ0π- mass spectrum shows a broad enhancement near 1.10 GeV/c2, which has the properties expected for the A1. © 1986 Springer-Verlag.

An upper limit for two-jet production in direct Υ{hooked}(1 S) decays
, Zeitschrift für Physik C Particles and Fields, Vol: 31, Pages: 181-184, ISSN: 0170-9739Using the ARGUS detector at the e+e- storage ring DORIS II at DESY, we have studied the distribution of various topological quantities on the Υ(1 S) resonance and in the nearby continuum. With the help of the second Fox-Wolfram moment we determine the two-jet contribution to direct Υ(1 S) decays to be less than 5.3% with 95% confidence. © 1986 Springer-Verlag.

An upper limit on the mass of the tau neutrino
, Physics Letters B, Vol: 163, Pages: 404-407, ISSN: 0370-2693Using the ARGUS detector at the e+e- storage ring DORIS II, we have measured the vτ energy spectrum in the decay π+π-π±vτ of τ leptons produced near s=10 GeV. From this energy spectrum, we derive an upper limit of m(vτ)<70 MeV c2 at the 95% confidence level. © 1985.

Observation of B-meson decay into J ψ
, Physics Letters B, Vol: 162, Pages: 395-399, ISSN: 0370-2693Using the ARGUS detector at the e+e- storage ring DORIS II, we have observed the colour suppressed decay B → J ψ X, with a branching ratio of (1.37+0.6-0.5)% for the mixture of charged and neutral B's produced on the Υ{hooked}(4S). From the momentum distribution of the J ψ we conclude that Br(B → J ψ X) < 0.7% (90% CL), for recoil masses, mx, less than 1 GeV/c2. © 1985.

Radiative decays of the Υ{hooked}(2S) into the three χ<inf>b</inf> states
, Physics Letters B, Vol: 160, Pages: 331-336, ISSN: 0370-2693The ARGUS detector at the e+e- storage ring DORIS II has been used as a pair spectrometer to study the photon transitions in the reaction Υ{hooked}(2S)→γχb(13P2,1, 0). Three photon lines were observed with energies (110.6±0.3±0.9) MeV, (131.7±0.3±1.1) MeV and (162.1±0.5±1.4) MeV, respectively. The corresponding branching ratios were found to be (9.8±2.1±2.4)%, (9.1±1.8±2.2)% and (6.4±1.4±1.6)%. Upper limits for full widths at the 90% confidence limit are 1.0 MeV for the χb(13P2) and 2.6 MeV for the other two states. © 1985.

The neutrino mass from the tritium beta spectrum in valine
, Physics Letters B, Vol: 159, Pages: 217-222, ISSN: 0370-2693The tritium beta spectrum in the valine molecule has been studied with the improved ITEP spectrometer. Emphasis has been put on the determination of the apparatus functions. An estimate resulting from the analysis is that the neutrino mass is larger than 20 eV. The mass difference of neutral 3H and 3He atoms calculated from the end-point energy is in good agreement with recent direct measurements of this value with an ion-cyclotron resonance spectrometer. © 1985.

Direct evidence for W exchange in charmed meson decay
, Physics Letters B, Vol: 158, Pages: 525-530, ISSN: 0370-2693Using the ARGUS detector at DORIS II, we have observed a signal of 36.7±8.0 events in the decay channel D0→Ks0φ. In the same data sample, we have observed the well established decay D0→Ks0π+π- , and find the ratio, Br(D)0→Ks0φ) Br(D)0→Ks0π+π -), to be 0.186±0.052. The substantial value of (0.99±0.32±0.17)% then derived for the branching ratio for D0→K0φ gives direct evidence that W exchange contributes D0 decay. © 1985.

Upper limit for the emission of monoenergetic photons in γ(1 S)- and γ(2 S)-meson decays
, Zeitschrift für Physik C Particles and Fields, Vol: 29, Pages: 167-173, ISSN: 0170-9739We report the results of a search for monoenergetic photons in the decay of both the Y(1 S)- and the Y(2 S)-meson. Photons converted in the beam tube or the drift chamber inner wall, and photons detected with the barrel shower counters of the ARGUS detector, respectively, have been used in the analysis. No narrow peak is observed in the energy interval 0.5 GeV≦Ey≦4.0 GeV. © 1985 Springer-Verlag.
