The inclusive jet production cross sections and triple-differential cross sections of top quark-antiquark pair production at the LHC at a center of mass energy of 13 TeV are used together with data of inclusive deep inelastic scattering to extract the parton distributions of the proton, the strong coupling constant and the top quark mass. In an additional analysis of the same data, the standard model cross section is extended with effective couplings for 4-quark contact interactions. [...]

The FLASH 1 beamline at DESY will be upgraded fromfixed to variable gap undulators in the next years. For this thevacuum beamline has to be adapted. [...]

For the new PETRA IV project at DESY, about 800 high 3 resolution BPMs will be installed with the readout electron­ics system based on MTCA.4 as technical platform. In order to fulfill the requested long-term drift requirement to be less than 1 micron over a period of six days ( one week of user operation), due to the machine-specific geometry the BPM cable paths have to be stabilized in addition. [...]

For the planned upgrade of synchrotron radiationsources PETRA (called PETRA IV) at DESY a muchhigher beam brilliance is requested. In order to measure accordingbeam positions and to control orbit stability to thecorresponding level of accuracy, a future high-resolutionBPM system has to deliver the necessary requirements onmachine stability. [...]

The Large Hadron Collider (LHC) at CERN is the first facility to produce millions of top quark events. In pp collisions, the dominant production mechanism for top quark pairs are the strong interactions, while single top quark production proceeds via electroweak interactions. [...]

The HL-LHC will ultimately increase the instantaneous luminosity by around a factor of four compared to Run-2 with up to 200 interactions per bunch crossing. This represents a major challenge in terms of triggering, with the trigger system divided into an initial first level trigger using custom electronics and a high level trigger composed of commodity computers.This poster will describe the first detailed and realistic reconstruction algorithms used for bottom quark jet identification at the CMS High Level Trigger for the upgraded detectors in the presence of 200 interactions together with the performance of its inputs.

The associated production of a single top quark and a Z boson includes the tZ coupling as well as the coupling of three vector bosons (WWZ) and is therefore a unique process to study the couplings of heavy particles in the SM. The top quark in this process is polarized due to its production through the weak interaction. [...]

Thanks to its high luminosity and center of mass energy, the future FCC-hh collider will allow us to probe processes with clean but rare final states that are unaccessible at the LHC. The study of diboson production processes poses a promising way of indirectly constraining New Physics in the context of the Higgs Boson. [...]
