The data were collected at the storage ring DORIS II at DESY with the ARGUS detector. We obtain upper limits of BRdir (ϒ (1S)→D *(2010)±+X)〈0.019 (forx p 〉0.2) and BRdir (ϒ(1S)→J/ψ+X)〈0.68×10−3, both at the 90% confidence level. From the prompt lepton analysis, a model dependent limit of BRdir (ϒ(1S)→Y c +X)〈0.034 (Y c denoting a charm-containing particle) is derived.Type of Medium: Electronic ResourceURL: -

Published 1992Staff ViewISSN: 1434-6052Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract An analysis of the decay τ-→π-π0 v τ has been performed using the ARGUS detector at the DORIS II storage ring. The branching ratio has been determined to be Br(τ-→π-π0 v τ=(22.6±0.4±0.9)%. The shape of the π-π0 invariant mass spectrum is found to be in good agreement with the predictions obtained using the conserved vector current (CVC) hypothesis, suggesting that the π-π0 system is produced in aJ P=1− state. An analysis of the measured decay angular distribution of the pions with respect to the flight direction of the π-π0 system demonstrates the vector nature of the coupling at the τv τ vertex. With the assumption of zerov τ mass thev τ spin has been shown to be $$J_{v_\tau } = \tfrac{1}{2} $$ .Type of Medium: Electronic ResourceURL: -

At a centre-of-mass energy $$\sqrt s = 9.36$$ GeV the ratio of the hadronic cross-section to the μ-pair cross section in lowest order QED has been determined to beR=3.46±0.03±0.13. In addition, we have measured the charged-particle multiplicities in non-resonant hadron production at $$\sqrt s = 10.47$$ GeV just below theB $$\bar B$$ threshold and in ϒ (4S) resonance decays. For the average charged-particle multiplicities in continuum events and ϒ(4S)→B $$\bar B$$ decays we obtain 〈n〉cont=8.35±0.02±0.20 and 〈n〉ϒ(4s)=10.81±0.05±0.23.Type of Medium: Electronic ResourceURL: -

While the main source of such events is the production of lepton pairs, the presence of an additional process is clearly indicated by the measured invariant mass distribution of the two particles and their angular distributions. We determine that the excess is mainly due to the decayf 0(1270)→π+π-. We derive a width Γ(f 0→γγ)=3.2±0.2±0.6 keV (statistical and systematic).Type of Medium: Electronic ResourceURL: -

Published 1986Staff ViewISSN: 1434-6052Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract Bose-Einstein correlations between pairs of charged particles produced ine + e − annihilation into hadronic final states have been studied as a function ofQ 2, the relative momentum squared of the two particles in their centre of mass, and as functions of various pairs of kinematic variables. The observed Bose-Einstein enhancement reveals correlation between the position and time of particle emission, and the space-time structure of the source is shown to differ from that of a pion fireball. While most features of the data are well accounted for in terms of the space-time structure of a simple string model, the correlations are better described by the simple function 1+αe −β Q 2. The implications of this result are discussed. The principal features of three particle correlations are explained in terms of the structure of the source inferred from the observed two particle correlations.Type of Medium: Electronic ResourceURL: -

The distribution of low energy particles in the 3-jet plane is found to be better described by the LUND color string model than by the independent jet model. The opposite is true for more energetic particles flowing between the 3 jets. The average transverse momenta in jets can be described with values of σ q between 350 and 500 MeV/c for the gluon jet.Type of Medium: Electronic ResourceURL: -
