Optimisation of a multivariate analysis technique for the $\mathbf{{t\bar{t}}}$ background rejection in the search for Higgs boson pair production in $\mathbf{b\bar{b}\tau^+\tau^-}$ decay channel with the CMS experiment at the LHC
This thesis reports the optimisation of a multivariate analysis technique for the search for Higgs boson pair ($HH$) production. $HH$ production gives an access to the Higgs boson trilinear self-coupling and is sensitive to the presence of physics beyond the Standard Model. Both resonant and nonreso...
