A search for Higgs boson pair production in the bb¯ bb¯ final state is carried out with up to 36.1 fb−1 of LHC proton-proton collision data collected at s=13 TeV with the ATLAS detector in 2015 and 2016. Three benchmark signals are studied: a spin-2 graviton decaying into a Higgs boson pair, a scalar resonance decaying into a Higgs boson pair, and Standard Model non-resonant Higgs boson pair produ

Results of a search for the pair production of photon-jets - collimated groupings of photons - in the ATLAS detector at the Large Hadron Collider are reported. Highly collimated photon-jets can arise from the decay of new, highly boosted particles that can decay to multiple photons collimated enough to be identified in the electromagnetic calorimeter as a single, photonlike energy cluster. Data fr

The essay gives a brief account of Brecht’s years of exile in Denmark, Sweden and Finland. Central to this story were his close relations with a number of cultural figures in the Nordic countries. The essay also discusses the way Brecht’s writing was transformed during his Nordic exile. It focuses on the fact that he wrote some of his best-known plays and developed his famous theory of Verfremdung

A search for supersymmetry in events with large missing transverse momentum, jets, and at least one hadronically decaying τ-lepton is presented. Two exclusive final states with either exactly one or at least two τ-leptons are considered. The analysis is based on proton-proton collisions at s=13 TeV corresponding to an integrated luminosity of 36.1 fb-1 delivered by the Large Hadron Collider and re

Fredrik N G Andersson diskuterar i bokens sjätte kapitel den gemensamma valutan eurons problem och framtid. Andersson påpekar att utmaningen för euron inte är nationalstatens återkomst utan att nationalstaten aldrig försvann. För att vinsterna med en gemensam valuta skall överstiga kostnaderna måste euroländerna förenas i en politisk union som gemensamt utformar regler för bland annat skatter, arb

Målet med denna studie är att ge ökad insikt i hur väl geoelektriska under-sökningar i en heterogen berggrund kan avbilda geologiska strukturer för att kunna vidare¬utveckla och anpassa framtida bergundersökningar.En ”bra” prognos av bergkvalitet ger bättre möjligheter till minskad risknivå vid projektering och upphandling. Omvänt gäller att osäkerheter i bergtekniska prognoser vad gäller bergets The aim of this project is to enhance the understanding of how geoelectrical investigations in a heterogeneous rock mass can image geological structures in order to develop and adapt future rock assessment methods.A "good" rock quality forecast provides better opportunities for reduced risk level in the design and procurement phases of a construction project. Conversely, uncertainties in a forecas

We consider global geometric properties of a codimension one manifold embedded in Euclideanspace, as it evolves under an isotropic and volume preserving Brownian flow of diffeomorphisms.In particular, we obtain expressions describing the expected rate of growth of the Lipschitz-Killing curvatures, or intrinsic volumes, of the manifold under the flow.These results shed new light on some of the intr

In this paper, we use a brand new dataset to estimate and compare wages for casually and annually hired workers in early modern southern Sweden. We ask whether men in either situation could have supported families on the basis of their earnings. Findings indicate that casual earners would have been able to out-earn annual employees for most of the period 1500–1850, but by the eighteenth century wh

We review some spherical wavelets systems and their statistical properties, with a view to applications in Cosmological/Astrophysical data analysis. In particular, we consider the analysis of Gaussian, isotropic random fields, and we focus on the geometric characterization of wavelet fields emerging in band-limited reconstructions. More precisely, we recall how to provide exact expression for Mink
