Description
A study of optimization of signal sensitivity in the search for the Di-Higgs event in the ATLAS experiment is presented where one of the Higgs bosons decays via the $H \xrightarrow{} b\Bar{b}$ channel and the other via $H \xrightarrow{} WW^{*}$ with $b\Bar{b}l\nu qq$ as the final state. Large irreducible background contamination from $t\Bar{t}$ decay significantly decreases the signal sensitivity in the Di-Higgs search. We employ ROOT's built-in Multivariate analysis tool (TMVA) to train new physics-motivated variables along with currently trained variables. An increment in the rejection of $t\Bar{t}$ background while keeping the signal efficiency high is observed.
