    Chargino production and decay in photon-photon collisions (2003)
    Springer
    The European physical journal 27 (2003), S. 135-143 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract. We discuss the pair production of charginos in collisions of polarized photons, $\gamma\gamma \rightarrow \tilde{\chi}_i^+ \tilde{\chi}_i^- (i = 1,2)$ , and the subsequent leptonic decay of the lighter chargino $\tilde{\chi}_1^+ \rightarrow \tilde{\chi}_1^0 e^+ \nu_e$ including the complete spin correlations. Analytical formulae are given for the polarization and the spin-spin correlations of the charginos. Since the production is a pure QED process the decay dynamics can be studied separately. For high energy photons from Compton backscattering of polarized laser pulses off polarized electron beams numerical results are presented for the cross section, the angular distribution and the forward-backward asymmetry of the decay positron. Finally we study the dependence on the gaugino mass parameter M1 and on the sneutrino mass for a gaugino-like MSSM scenario.

    Neutralinos in E $_{6}$ inspired supersymmetric U(1)' models (2002)
    Springer
    The European physical journal 23 (2002), S. 149-162 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract. The neutralino sector in $\mathrm{E_6}$ inspired supersymmetric models with extra neutral gauge bosons and singlet Higgs fields contains additional gaugino and singlino states compared to the MSSM. We discuss the neutralino mixing in rank-5 and rank-6 models and analyze the supersymmetric parameter space where the light neutralinos have mainly singlino or MSSM character. The neutralino character, resonance effects of the new gauge bosons and, assuming mSUGRA-type RGEs, different selectron masses lead to significant differences between the MSSM and the extended models in neutralino production at an $e^+e^-$ linear collider. Beam polarization may improve the signatures to distinguish between the models. In an appendix, we present the mass terms of the gauge bosons, charginos and sfermions which show a significant different mass spectrum than in the MSSM and give all relevant neutralino couplings.

    Precision measurements of Higgs-chargino couplings in chargino pair production at a muon collider (2003)
    Springer
    The European physical journal 29 (2003), S. 587-595 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract. We study chargino pair production on the heavy Higgs resonances at a muon collider in the MSSM. At $\sqrt{s} \approx 350$ GeV cross sections up to 2 pb are reached depending on the supersymmetric scenario and the beam energy spread. The resonances of the scalar and pseudoscalar Higgs bosons may be separated for $\tan\beta 〈 8$ . Our aim is to determine the ratio of the chargino couplings to the heavy scalar and pseudoscalar Higgs boson independently of the specific chargino decay characteristics. The precision of the measurement depends on the energy resolution of the muon collider and on the error in the measurement of the cross sections of the non-Higgs channels including an irreducible standard model background. With a high energy resolution the systematic error can be reduced to the order of a few percent.

    Notes: Für den Hochtemperatur-Winkler-Prozeß wurde der Verlauf der Gaszusammensetzungen in Abhängigkeit von der Fluidatbetthöhe bestimmt. Zur quasistationären Beschreibung der Umsetzungen dienen Konsekutivreaktionen, wobei aufgrund des hohen Temperaturniveaus die Rückreaktionen unberücksichtigt bleiben können. Die Umsetzung von natürlichen Kohlenstoff-Trägern z. B. mit Luft läßt sich durch zwei Geschwindigkeitskonstanten beschreiben, die auf Konsekutivreaktionen zurückgehen.

    Vergasung von Rohkohle mit dem Eigenwasser (1970)

    Notes: In einer Versuchsanlage wurde Rohbraunkohle mit ihrem Eigenwasser in einem elektrisch beheizten Reaktionsrohr vergast. Bereits bei Temperaturen von 800 bis 900 °C werden hohe Umsatzgrade und gute Gasqualitäten erreicht. Die Versuchsergebnisse werden mit theoretischen Berechnungen verglichen. Die Vergasung im obigen Temperaturbereich ist deshalb interessant, weil erwartet wird, daß Hochtemperatur-Kernreaktoren in naher Zukunft bei diesen Temperaturen ihre thermische Energie liefern können. Die beschriebene Rohbraunkohle-Vergasung kann auch dann wirtschaftlich betrieben werden, wenn diese Kohle als alleinige Wärmequelle dient.

    The lifecycle of instability features measured from the Andes Lidar Observatory over Cerro Pachon on March 24, 2012 (2014)
    Wiley
    Details
    Publication Date: 2014-07-13
    Description: The Aerospace Corporation's Nightglow Imager (ANI) observes nighttime OH emission (near 1.6 microns) every 2 seconds over an approximate 73 degree field of view. ANI had previously been used to study instability features seen over Maui. Here we describe observations of instabilities seen from 5 to 8 UT on 24 March 2012 over Cerro Pachon Chile, and compare them with previous results from Maui, with theory, and with Direct Numerical Simulations (DNS). The atmosphere had reduced stability because of the large negative temperature gradients measured by a Na lidar. Thus, regions of dynamical and convective instabilities are expected to form depending on the value of the Richardson number. Bright primary instabilities formed with a horizontal wavelength near 9 km and showed the subsequent formation of secondary instabilities, rarely seen over Maui, consistent with the primaries being dynamical instabilities. The ratio of the primary to secondary horizontal wavelength was greater over Chile than over Maui. After dissipation of the instabilities smaller-scale features appeared with sizes in the buoyancy subrange between 1.5 and 6 km. Their size spectra were consistent with the model of Weinstock (1978) if the turbulence is considered to be increasing. The DNS results produce secondary instabilities with sizes comparable to what is seen in the images although their spectra are somewhat steeper than is observed. However, the DNS results also show that after the complete decay of the primary features scale sizes considerably smaller than 1 km are produced and these cannot be seen by the ANI instrument.
