    Uncovering quasi-degenerate Kaluza-Klein Electro-Weak gauge bosons with top asymmetries at the LHC

    No full text
    By exploiting the correlation between charge and spin polarisation asymmetries in t-tbar, we show that combining the two observables could identify the presence of quasi-degenerate states in a resonant signal at the LHC. As an example, we investigate experimental signatures emerging in top-antitop final states in the context of a model where the Standard Model Electro-Weak sector is allowed to propagate in large extra--dimensions of TeV-1 size while the colour sector is localised. Assuming current experimental constraints from the 7 and 8 TeV runs and taking into account the estimated top (anti-top) reconstruction efficiencies, we find that the 14 TeV upgraded LHC with the planned integrated luminosity L=100 fb-1 could access these quasi-degenerate multiple resonances and explore for the first time the rich phenomenology in the asymmetry observables. The main outcome would be having measurable quantities, complementary to the usual total and differential cross sections, capable of distinguishing a quasi-degenerate multiply resonant spectrum from a 'standard' single resonance that could present a similar signal in a bump hunt analysis

    An opening Keynote presentation by Lauren Klein introduced by Evan Peck. Lauren Klein is Winship Distinguished Research Professor and Associate Professor in the departments of English and Quantitative Theory & Methods at Emory University, where she also directs the Digital Humanities Lab. Before moving to Emory, she taught in the School of Literature, Media, and Communication at Georgia Tech. Klein works at the intersection of digital humanities, data science, and early American literature, with a focus on issues of gender and race. She is the author of An Archive of Taste: Race and Eating in the Early United States (University of Minnesota Press, 2020) and, with Catherine D’Ignazio, Data Feminism (MIT Press, 2020). With Matthew K. Gold, she edits Debates in the Digital Humanities, a hybrid print-digital publication stream that explores debates in the field as they emerge. Her work has appeared in leading humanities journals including PMLA, American Literature, and American Quarterly; and at technical conferences including NACCL, EMNLP, and IEEE VIS.

    The "fundamental theorem" for the algebraic K-theory of spaces. II: The canonical involution

    Hüttemann T, Klein JR, Vogell W, Waldhausen F, Williams B. The "fundamental theorem" for the algebraic K-theory of spaces. II: The canonical involution. Journal of Pure and Applied Algebra. 2002;167(1):53-82.Let X --> A(X) denote the algebraic K-theory of spaces functor. In the first paper of this series, we showed A(X x S-1) decomposes into a product of a copy of A(X), a delooped copy of A(X) and two homeomorphic nil terms. The primary goal of this paper is to determine how the "canonical involution" acts on this splitting. A consequence of the main result is that the involution acts so as to transpose the nil terms. From a technical point of view, however, our purpose will be to give another description of the involution on A(X) which arises as a (suitably modified) P.-construction. The main result is proved using this alternative discription. (C) 2002 Elsevier Science B.V. All rights reserved

    Betriebliche Gesundheitsfoerderung in Klein- und Mittelbetrieben

    No full text
    'Innovative Ansaetze der Praevention und Gesundheitsfoerderung in der Arbeitwelt sind in den 90er Jahren vor allem in groesseren Unternehmen entwickelt und erprobt worden. Insbesondere die Krankenkassen haben, gestuetzt auf den Auftrag des Sozialgesetzbuches V, viele betriebliche Projekte initiiert. Kleinere Unternehmen waren dagegen oft schon mit der Umsetzung von Arbeitsschutzvorschriften ueberfordert. Die Uebertragung des Auftrages, sich der 'Verhuetung arbeitsbedingter Gesundheitsgefahren' anzunehmen, im Sozialgesetzbuch VII 1996 hat die Berufsgenossenschaften vor neue Herausforderungen gestellt. Gemeinsam mit den Innungskrankenkassen, aber auch anderen Krankenkassen haben sie begonnen, sich intensiv um die Entwicklung von Konzepten fuer eine ganzheitliche betriebliche Gesundheitspolitik in kleinen und mittleren Unternehmen und im Handwerk zu kuemmern. Einen repraesentativen Ausschnitt aus den vielen innovativen Ansaetzen bildet der vorliegende Band ab. In 17 Beitraegen stellen 22 Autoren von praxisnahen Forschungseinrichtungen, Berufsgenossenschaften und Krankenkassen ihre Konzepte und Praxisbeispiele vor. Die Fallstudienpalette reicht von Gesundheitsfoerderprojekten der Norddeutschen Metall BG und der BG Nahrung und Gaststaetten ueber Pilotvorhaben der Kassen - AOK Niedersachsen, IKK Nordrhein, Gmuender Ersatzkasse - bis zu Beispielen aus dem Bereich Innung/ Handwerk -Baecker, Bauhandwerk, Tischler, Goldschmiede, Zahnarzthelferinnen, VAG-Vertragshaendler u.a. Deutlich wird in dem praxisnahen und informativen Band, dass sich im institutionalisierten Arbeitsschutz in betraechtlichem Masse 'Neues Denken' ausbreitet und dass in einer zunehmenden Zahl auch von Klein- und Mittelbetrieben die Erkenntnis vom Nutzen der Betrieblichen Gesundheitsfoerderung und der Verhuetung arbeitsbedingter Gesundheitsgefahren waechst.'
