Description
Since the Higgs boson was discovered in 2012, various production and decay modes of the Higgs have been measured. One production mode that has not yet been observed is Higgs production in association with a top quark pair. Discovery of this mode would yield a direct measurement of the Higgs coupling strength to the top quark, a measurement not easily accessible. This talk presents an ongoing analysis searching for Higgs boson production in association with a top quark pair in the $H \rightarrow b\bar{b}$ decay mode, in the lepton + jets final state. Multivariate techniques are used to separate signal-like events from background-like events. The reported studies use data recorded by the ATLAS experiment at $\sqrt{s}$ = 13 TeV during 2015 and 2016.
