Note: A project is proposed in which advanced studies of top quark interactions with heavy bosons will be performed within the CMS experiment at the CERN Large Hadron Collider (LHC). In particular, the structure of the interaction between the top quark and the Z boson will be measured directly for the first time. The LHC is expected to deliver a huge data sample of proton-proton collisions until 2023. The data provides unique opportunities for breakthrough measurements and searches for new phenomena. Most prominently, processes with combinations of several heavy particles in the final state are becoming accessible with precision for the first time. In many scenarios beyond the current standard model of particle physics, the heaviest known elementary particles, the top quark, the recently discovered Higgs boson, and the vector bosons W and Z, play key roles. Therefore, it is essential to achieve a deep understanding about the interaction of heavy particles, both in the context of the standard model and in the presence of new phenomena. The project consists of a coherent set of precision measurements of rare standard model processes and innovative searches for new henomena. While each of the foreseen studies will provide valuable results in itself, the particular strength of the project lies in the coherence of the analyses and gain through their combination. With its engagement and its expertise in LHC physics, both experimental and theoretical, DESY offers a uniquely attractive environment for this project and the Karlsruhe Institute of Technology is an outstanding and obvious university partner.All known publications ...
