- Im Jahre 2006 hat Mario Bellini den Architekturwettbewerb für die Sanierung der Firmenzentrale der Deutschen Bank AG in Frankfurt am Main gewonnen. Unter seiner Leitung ist in der Eingangshalle eine herausragende Skulptur entstanden. Die Sphäre – der architektonische Mittelpunkt des neu gestalteten Foyers zwischen den beiden Türmen, symbolisiert Stabilität und Stärke, aber zugleich auch Dynamik und Wandel.Der Entwurf des Architekten sah eine 16 m durchmessende Kugel vor, die mit Bändern umwickelt zu sein scheint und zwischen den beiden Türmen der Bank klemmt. Dieses Konzept wurde durch ein interdisziplinäres Team bestehend aus dem verantwortlichen Entwurfsarchitekt Giulio Castegini (Mario Bellini Architects), den Ingenieuren Oliver Tessmann und Mark Fahlbusch (Bollinger Grohmann Ingenieure) und Oliver Drawer der ausführenden Firma (Arnold AG) weiterentwickelt.

- The European Spallation Source (ESS), which is under construction in Lund (Sweden), will be the next leading neutron facility with an unprecedented brilliance and novel long-pulse time structure. A long-pulse source not only provides a high time-average flux but also opens the possibility to tune the resolution by using pulse shaping choppers. Thus, an instrument can readily be operated in either a high flux or a high resolution mode. Several of the shorter instruments at the ESS will employ Wavelength Frame Multiplication (WFM) in order to enable a sufficient resolution while offering a continuous and broad wavelength range. A test beamline was operated until the end of 2019 at the research reactor in Berlin to test components and methods, including WFM, in order to prepare the new facility for the operation of neutron instruments and successful first science. We herein demonstrate the implementation of WFM for reflectometry. By selecting a short pulse mode under the same geometrical configuration, we compare and discuss the results for two reference samples. The reported experiments not only serve to prove the reliability of the WFM approach but also, for the first time, demonstrate the full instrument control, data acquisition and data reduction chain that will be implemented at the ESS.

- Studies of the spin and parity quantum numbers of the Higgs boson in the [Formula: see text] final state are presented, based on proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 20.3 fb[Formula: see text] at a centre-of-mass energy of [Formula: see text] TeV. The Standard Model spin-parity [Formula: see text] hypothesis is compared with alternative hypotheses for both spin and CP. The case where the observed resonance is a mixture of the Standard-Model-like Higgs boson and CP-even ([Formula: see text]) or CP-odd ([Formula: see text]) Higgs boson in scenarios beyond the Standard Model is also studied. The data are found to be consistent with the Standard Model prediction and limits are placed on alternative spin and CP hypotheses, including CP mixing in different scenarios.
