A fine-tuned CMS tracking detector to reveal new physics using top quarks

Abstract: The talk will highlight latest results on top quark physics at CMS employing pp collision data at a center-of-mass energy of 13 TeV. With millions of top quarks already collected at the LHC top quark physics enters the precision era, with percent level uncertainties even in two-dimensional differential measurements. Deviations between theory and experimental measurements might indicate hints for new physics and the talk discusses current bottlenecks and perspectives in top quark physics, e.g. the intimate connection of the top quark to the Higgs Boson is scrutinized by highly precise direct measurements of the top quark mass. Looking into the future: the high-luminosity phase of the LHC provides unprecedented numbers of proton-proton collisions and in turn enormous amounts of top quarks for extremely precise measurements. The second part of the talk will outline the design and manufacturing challenges of a future tracking detector in a high radiation & rate environment, and discusses R&D towards scalable minimal mass detector support structures by machine learning enhanced design & manufacturing. The talk concludes with presenting a top quark physics performance study showing the non-SM discovery potential at the HL-LHC.
