BDTs in the Search for $\mathrm{t \bar{t} H}$ Production with Higgs Decays to $\mathrm{b\bar{b}}$ at ATLAS

An observation of Higgs boson production in association with a top quark pair ($\mathrm{t \bar{t} H}$) provides a direct measurement of the top quark Yukawa coupling and probes the Standard Model. The ATLAS search for $\mathrm{t \bar{t} H}$, $\mathrm{H\rightarrow b\bar{b}}$ relies on Boosted Decision Trees for Higgs reconstruction and signal-background discrimination, which is presented for the preliminary results on the $\sqrt{s}=$~13~TeV dataset.
