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 Decisio...

description 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.

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.An observation of Higgs boson production in association with a top quark pair ($\mathrm{t \overline{t}H}$) is a key outstanding measurement of the LHC programme. Boosted Decision Trees are vital for the search of $\mathrm{t \overline{t}H}$, playing a role in event reconstruction and discriminating signal from a large background. The use of BDTs in the ATLAS search for $\mathrm{t \overline{t}H}$, $\mathrm{H \rightarrow b \overline{b}}$ is presented for the preliminary results on the $\sqrt{s} = 13$ TeV, $13.2$ fb$^{-1}$ dataset.ATL-PHYS-PROC-2017-214oai:cds.cern.ch:22892582017-10-16
