Probing CP-Violation in Top-HiggsInteractions

The search for physics beyond the standard model of particle physics that canexplain the unsolved mysteries of the universe, such as the matter-antimatter asymmetry,is of high importance in todays research. The interaction of quarks with theHiggs boson is a candidate for such physics, possibly resulting in a new source ofCP-violation. This work analyses multiple observables on their sensitivity to theCP coupling in this interaction by performing an analysis using simulated data fort ¯th production in pp collider events. The data is evaluated on parton level both beforeand after acceptance cuts are applied. In addition, a detector simulation for theCMS detector at the LHC is executed. A hypothesis test that can evaluate the observablesis presented and their usability in a real detector experiment is discussed.In the final state leptons a promising candidate for observables sensitive to the CPcoupling in the process is found
