In the last ten years we have expe rienced the start and the first triumphs of the Large Hadron Collider (LHC ) located at CERN in Geneva\, Switzerland. Surely\, the discovery of a Sta ndard Model-like Higgs boson in 2012 stands out within this context. But e ven though\, that further major findings like Physics beyond the Standard Model eluded us so far\, the quest for understanding our elementary nature is ongoing under full steam. One of the outstanding important checks is t he determination if the Higgs boson is really the Higgs boson predicted by the Standard Model. An important puzzle piece in this aspect will be the discovery of the ttH signal process providing us with a direct measurement of the Top-Higgs-Yukawa coupling. The search for ttH in the bbar decay ch annel benefits from the large branching fraction of 58% for the Higgs to b bar decay. At the same time\, the large irreducible tt+bb background poses a major challenge and requires the use of advanced analysis techniques. A further crucial ingredient is the estimation and modelling of the tt+bb b ackground via MC event generators which is still afflicted with large theo retical uncertainties.
\n\nThis talk will discuss the work on the up coming ttH(Hbb) analysis covering the 2016 LHC data set and ongoing work t o reduce the uncertainties related to the tt+bb background. Furthermore\, the talk will deliver a glimpse in the future of experimental particle phy sics by interspersing examples of novel techniques used in the analysis\, e.g. the application of Neural Networks as a classifier\, Continuous integ ration as an improvement of the analysis workflow\, and NLO event generati on for obtaining more accurate simulation data.
