Abstract:

We have observed exclusive production of K+K- and KSOKSO pairs and the excitation of the f′(1515) tensor meson in photon-photon collisions. Assuming the f′ to be production in a helicity 2 state, we determine Λ(f′ → γγ) B(f′ → KK) = 0.11 ± 0.02 ± 0.04 keV. The non-strange quark of the f′ is found to be less than 3% (95% CL). For the θ(1640) we derive an upper limit for the product Λ(θ rarr; γγ KK) < 0.03 keV (95% CL). © 1983.

Abstract:

A high statistics experiment was performed on Bhabha scattering at energies between 14 and 34 GeV. Good agreement with QED was observed. The combined data on Bhabha scattering and μ pair production were found to agree with the standard theory of electroweak interaction giving sin2 θ = 0.27-0.07+0.06. Assuming for the Z0 mass a value of 90 GeV the leptonic weak coupling constants were determined to gV2 = -0.04 ± 0.06 and gA2 = 0.35 ± 0.09. A search for scalar leptons sets lower limits on the mass of scalar electrons ofMse > 16.6 GeV and of scalar muons of Msμ > 16.4 GeV. © 1982.

Abstract:

We have observed ρ{variant}0 production in e+e- annihilation to hadrons at high energies. The differential cross section at a centre of mass energy W, of 34 GeV, is presented. In the range 0.2< x < 0.7, we measure 0.33 ± 0.06 (stat.) ± 0.07 (syst.), 0.22 ± 0.06 ± 0.05 and 0.22 ± 0.02 ± 0.05 ρ{variant}0/event at W = 14, 22 and 34 GeV respectively. © 1982.

Abstract:

The scale cross section sdσ dxp for inclusive charged-particle production in e+e- annihilation has been studied for c.m. energies W between 12.0 and 36.7 GeV. Scale breaking is observed. For xp>0.2 the cross section decreases by ≈20% when W increases from 14 to 35 GeV. The production angular distribution was used to separate the longitudinal and transverse cross-section contributions and to determine the ratio of the structure functions mW1 and vW2. © 1982.
