Status and Plans on Research for Associated Production of the Higgs Boson and a Top-quark Pair with the ATLAS Detector

Abstract: After the observation (>5 standard deviations) of the ttH coupling was released in June 2018, the goal is the measurement of the ttH coupling with high precision. The fundamental relation that the Higgs coupling strength is proportional to the mass of the associated fermion pair to which it gives mass can be tested best with the heaviest fermion, the top quark. The focus of the IEAP group is on the analysis of a ttH production, where the Higgs boson decays into a pair of tau-leptons. The signature in the detector is a pair of light leptons with same electric charge and the detection of a hadronically decaying tau lepton. This specific decay channel has proven over the years to give significant sensitivity to the ttH observation. This analysis is particularly challenging as the simulations of the background rates have insufficient precision and a data-driven background estimate method is applied. In this presentation the status and plans for the analysis of the 2015-2017 data is addressed.
