The prospects of observing the di-Higgs production in the Standard Model (SM) is explored. We choose final states based on considerable production rate and cleanliness. Standard cut-based and multivariate analyses using the Boosted Decision Tree (BDT) algorithm is performed at the high luminosity run of the 14 TeV LHC (HL-LHC) and we got a combined signal significance of � 2.1. For the proposed high energy upgrade of the LHC (HE-LHC) at, we do multivariate analyses using BDT algorithm, the XGBoost toolkit and Deep Neural Network (DNN), and we observe a discovery prospect with > 5� significance for the Higgs pair production. © Published under licence by IOP Publishing Ltd.
