Abstract: The associated production of a top-quark pair with a Higgs boson (ttH) directly probes the top-Higgs Yukawa coupling, a key parameter in the Standard Model. This study focuses on the ttH(bb) channel with dileptonic top decays, using Run 3 CMS simulation. Building on previous measurements with Run 2 data, we optimize event selection and background suppression to enhance signal significance. A binned maximum likelihood fit is employed to extract the expected signal significance, serving as a figure of merit for the optimization.
