The associated production of a top-quark pair with a Higgs boson (ttH) directly probes the top-Higgs Yukawa coupling in the Standard Model. This study examines the ttH(bb) channel in the semileptonic and dileptonic final states, using Run 3 CMS simulation data. For a robust, data-driven estimation of the dominant tt+bb background the final state is reconstructed using advanced machine learning techniques for jet assignment. To use the invariant mass of jets assigned to the Higgs candidate as an unbiased fit variable, the reconstruction is decorrelated from the Higgs mass.
