    Description: 〈span〉〈div〉Abstract〈/div〉A few, thin, Mississippian siliciclastic limestone beds, interbedded with ammonoid (uppermost 〈span〉Eumorphoceras〈/span〉 Zone)-bearing shales within the South Syncline Ridge section on the Nuclear Test Site in southern Nevada, contain an abundant, low-diversity assemblage of late Serpukhovian/late Chesterian calcareous foraminifers dominated by the archaediscaceans 〈span〉Neoarchaediscus altiluminis〈/span〉, 〈span〉Brenckleina rugosa〈/span〉, 〈span〉Eosigmoilina robertsoni〈/span〉, and 〈span〉Betpakodiscus〈/span〉 of the group 〈span〉B〈/span〉. 〈span〉attenuatus〈/span〉. These limestone beds were deposited in a shallow-water, clastic facies of the Scotty Wash Formation and, based on common conodont occurrences, correlate southeast to the Bird Spring Formation below the Mississippian-Pennsylvanian GSSP at Arrow Canyon, Nevada. The South Syncline Ridge foraminifers are comparable to those found in coeval beds at Arrow Canyon and represent the only other known foraminiferal assemblage to exist in association with uppermost 〈span〉Eumorphoceras〈/span〉 Zone ammonoids in North America outside of Arkansas in the southern Midcontinent. Reconciliation of regional conodont and ammonoid zonations shows that the range of eosigmoiline foraminifers (〈span〉E〈/span〉. 〈span〉robertsoni〈/span〉 and 〈span〉B〈/span〉. 〈span〉rugosa〈/span〉), now generally considered an upper Serpukhovian index, extends from a position either just below or at the lower-upper boundary of the Serpukhovian Stage into the lower part of the Bashkirian Stage in North America; their upper range falls within the lower part of the 〈span〉Homoceras〈/span〉 ammonoid zone beginning in the upper part of the Serpukhovian Stage. Discussion of the foraminiferal taxa includes support for retaining the genus 〈span〉Betpakodiscus〈/span〉 rather than synonymizing it under 〈span〉Tubispirodiscus〈/span〉, as proposed by some specialists during the past few years.〈/span〉

    Notes: Abstract. We employ data taken by the JADE and OPAL experiments for an integrated QCD study in hadronic e $^+$ e $^-$ annihilations at c.m.s. energies ranging from 35 GeV through 189 GeV. The study is based on jet-multiplicity related observables. The observables are obtained to high jet resolution scales with the JADE, Durham, Cambridge and cone jet finders, and compared with the predictions of various QCD and Monte Carlo models. The strong coupling strength, $\alpha_s$ , is determined at each energy by fits of ${\cal O}(\alpha_s^2)$ calculations, as well as matched ${\cal O}(\alpha_s^2)$ and NLLA predictions, to the data. Matching schemes are compared, and the dependence of the results on the choice of the renormalization scale is investigated. The combination of the results using matched predictions gives \[\alpha_s(M_{Z^0})=0.1187^{0.0034}_{0.0019}.\] The strong coupling is also obtained, at lower precision, from ${\cal O}(\alpha_s^2)$ fits of the c.m.s. energy evolution of some of the observables. A qualitative comparison is made between the data and a recent MLLA prediction for mean jet multiplicities.

    Notes: Abstract. The process ${\rm e^+e^-}\to \gamma \gamma (\gamma)$ is studied using data recorded with the OPAL detector at LEP. The data sample corresponds to a total integrated luminosity of 25.38 pb $^{-1}$ taken at centre-of-mass energies of 130–172 GeV. The measured cross-sections agree well with the expectation from QED. In a combined fit using data from all centre-of-mass energies, the angular distribution is used to obtain improved limits on the cut-off parameters: $\Lambda_+ 〉 195$ GeV and $\Lambda_- 〉 210$ GeV (95% CL). In addition, limits on non-standard ${\rm e^+e^-}\gamma$ couplings and contact interactions, as well as a 95% CL mass limit for an excited electron, $M_{\mathrm{e^{\ast}}} 〉 194$ GeV for an ${\rm e^+e^-}\gamma$ coupling $\kappa = 1$ , are determined.

    Notes: Abstract. An update of the searches for charginos and neutralinos in DELPHI is presented, based mainly on recent data collected at centre-of-mass energies of 161 GeV and 172 GeV. No signal is found. For a sneutrino with mass above 300 GeV/ $c^2$ and a mass difference between the chargino and the lightest neutralino above 10 GeV/ $c^2$ , the lower limit at 95% confidence level on the chargino mass ranges from 84.3 GeV/ $c^2$ to the kinematical limit (86.0 GeV/ $c^2$ ), depending on the mixing parameters. The limit decreases for lower chargino-neutralino mass differences. The limit in the case of a light sneutrino is 67.6 GeV/ $c^2$ , provided that that there is no light sneutrino with a mass within 10 GeV $/c^2$ below the chargino mass. Upper limits on neutralino pair production cross-sections of about a picobarn are derived. The $(\mu,M_2)$ domain excluded in the MSSM-GUT scenario is determined by combining the neutralino and chargino searches. These results imply a limit on the mass of the lightest neutralino which, for a heavy sneutrino, is constrained to be above 24.9 GeV/ $c^2$ for tan $\beta \ge 1$ . The search has also been extended to the case where the lightest neutralino is unstable and decays into a photon and a gravitino.

    Notes: Abstract. A search for the resonant production of high mass photon pairs associated with a leptonic or hadronic system has been performed using a total data sample of 25.7 pb $^{-1}$ taken at centre-of-mass energies between 130 GeV and 172 GeV with the OPAL detector at LEP. The observed number of events is consistent with the expected number from Standard Model processes. The observed candidates are combined with search results from $\sqrt{s} \approx M_{\mathrm Z}$ to place limits on $B({\mathrm H}^{0} \to \gamma\gamma$ ) within the Standard Model for Higgs boson masses up to 77 GeV, and on the production cross section of any scalar resonance decaying into di-photons. Upper limits on $B({\mathrm H}^{0} \to \gamma\gamma)\times\sigma({\mathrm e}^+{\mathrm e}^-\to{\mathrm H}^{0}{\mathrm Z}^{0})$ of 290–830 fb are obtained over $40 〈 M_{\mathrm H} 〈 160$ GeV. Higgs scalars which couple only to gauge bosons with Standard Model strength are ruled out up to a mass of 76.5 GeV at the 95% confidence level.
