Zum 80. Todestag von Ernst Toller (1893–1939) widmet sich TEXT+KRITIK der ganzen Breite seiner schriftstellerischen Produktion, die nicht nur in enger Verbindung zur Politik, sondern auch zu den modernen Massenmedien steht. Der Schriftsteller Ernst Toller ist im kollektiven Gedächtnis vor allem als Autor von Stücken wie "Masse Mensch" und "Hinkemann" sowie der Selbstbiografie "Eine Jugend in Deutschland" präsent. Was er darüber hinaus an literarischen Werken gescha?en hat, ist dagegen weitgehend in Vergessenheit geraten. Untersucht werden neben den erwähnten Texten die Gedichte, die proletarischen Massenfestspiele, die Arbeiten für Rundfunk und Kino, die Reiseberichte und die Aufzeichnungen zum Spanischen Bürgerkrieg sowie die Briefe, die jüngst gesammelt ediert wurden. Außerdem enthält das Heft eine auf den neuesten Forschungsstand gebrachte Chronik zu Leben und Werk und eine kommentierte Auswahlbibliografie. Ergänzt wird die Publikation durch den Abdruck zweier Texte, die in der Toller-Philologie bisher unbekannt waren: die Erzählung "Tagebuch eines seltsamen Mädchens" und das Szenarium "Krieg – Frieden", sowie durch Jan Wagners Übersetzung von W. H. Audens Epitaph "In Gedenken an Ernst Toller".

Abstract: In this thesis a search for a CP-odd Higgs boson A decaying into a Z boson and a neutral CP-even Higgs boson h with a mass of 125 GeV is described. The search is based on proton-proton collision data at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector in the years 2015 and 2016 corresponding to an integrated luminosity of 36/fb. Final states, where the Z boson decays into pairs of electrons, muons or neutrinos and the h boson into bottom-quark pairs, are considered. The presence of neutrinos is inferred by a momentum imbalance in the transverse plane, the bottom-quark pairs are reconstructed either as two small-radius or one large-radius calorimeter jet(s). The reconstructed invariant or transverse mass distributions of the Zh candidates are searched for the presence of localised excesses above the expectation from known Standard Model processes. No evidence for an A-boson signal is found. Upper limits on the A-boson production cross-section times the branching fractions for A-boson decays into Zh and h-boson decays to bottom-quark pairs are derived at the 95% confidence level for A bosons with masses between 220 GeV and 2 TeV; they range between 0.0019 pb and 0.81 pb. The results are interpreted in the context of Two-Higgs-Doublet Models. Furthermore, a novel method to calibrate the b-tagging efficiency for c-quark jets is described. It is demonstrated for the standard b-tagging algorithm of the ATLAS experiment in Run 1 using proton-proton collision data at a centre-of-mass energy of 7 TeV collected with the ATLAS detector in the year 2011. The calibration uses a sample of c jets obtained from events, where a W boson is produced in association with a single c quark; the resulting c jet is identified by a muon stemming from the semileptonic c-hadron decay. The measured c-jet tagging efficiencies are presented relative to the corresponding efficiencies in simulated W+c events as scale factors. The measured scale factors are extrapolated using a simulation-based and data-supported procedure to obtain scale factors valid for inclusive samples of c jets. Their uncertainties range between 5% and 13 %.

Abstract: A summary of the constraints from the ATLAS experiment on R-parity-conserving supersymmetry is presented. Results from 22 separate ATLAS searches are considered, each based on analysis of up to 20.3 fb−1 of proton-proton collision data at centre-of-mass energies of s√=7 and 8 TeV at the Large Hadron Collider. The results are interpreted in the context of the 19-parameter phenomenological minimal supersymmetric standard model, in which the lightest supersymmetric particle is a neutralino, taking into account constraints from previous precision electroweak and flavour measurements as well as from dark matter related measurements. The results are presented in terms of constraints on supersymmetric particle masses and are compared to limits from simplified models. The impact of ATLAS searches on parameters such as the dark matter relic density, the couplings of the observed Higgs boson, and the degree of electroweak fine-tuning is also shown. Spectra for surviving supersymmetry model points with low fine-tunings are presented

Abstract: A search for squarks and gluinos in final states containing hadronic jets, missing transverse momentum but no electrons or muons is presented. The data were recorded in 2015 by the ATLAS experiment in s√=13 TeV proton-proton collisions at the Large Hadron Collider. No excess above the Standard Model background expectation was observed in 3.2 fb−1 of analyzed data. Results are interpreted within simplified models that assume R-parity is conserved and the neutralino is the lightest supersymmetric particle. An exclusion limit at the 95 % confidence level on the mass of the gluino is set at 1.51 TeV for a simplified model incorporating only a gluino octet and the lightest neutralino, assuming the lightest neutralino is massless. For a simplified model involving the strong production of mass-degenerate first- and second-generation squarks, squark masses below 1.03 TeV are excluded for a massless lightest neutralino. These limits substantially extend the region of supersymmetric parameter space excluded by previous measurements with the ATLAS detector
