Higgs Self-Coupling at the HL-LHC and HE-LHC / Adhikary, Amit (Bangalore, Indian Inst. Sci.) ; Banerjee, Shankha (CERN) ; Barman, Rahool Kumar (Oklahoma State U.) ; Bhattacherjee, Biplob (Bangalore, Indian Inst. Sci.) ; Niyogi, Saurabh (Gokhale Coll., Calcutta)
The Higgs boson pair production has been studied in multifarious final states at the HL-LHC and HE-LHC. The optimisation for separating signal from the backgrounds are performed using cut-based and machine learning algorithms like BDT, XGBoost toolkit and DNN. [...]

Prospects of non-resonant Higgs pair production at the HL-LHC and HE-LHC / Adhikary, Amit (Bangalore, Indian Inst. Sci.) ; Banerjee, Shankha (Durham U., IPPP) ; Barman, Rahool Kumar (IACS, Kolkata) ; Bhattacherjee, Biplob (Bangalore, Indian Inst. Sci.) ; Niyogi, Saurabh (Gokhale Coll., Calcutta)
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. [...]

Prospects of non-resonant and resonant Higgs pair production at the HL-LHC / Adhikary, Amit (Warsaw U.) ; Banerjee, Shankha (CERN) ; Barman, Rahool Kumar (Oklahoma State U.) ; Bhattacherjee, Biplob (Bangalore, Indian Inst. Sci.) ; Niyogi, Saurabh (Gokhale Coll., Calcutta)
We combined multiple final states ensuing from non-resonant Higgs pair production by optimising over each final state using multivariate techniques and put bounds on the self-coupling of Higgs by employing the log-likelihood confidence level hypothesis test. Further, we calculate the production cross-section limits from multifarious heavy Higgs decay channels, including resonant di-Higgs production, in a model-independent way and draw its impact on the MSSM parameter space at the HL-LHC..

Revisiting the non-resonant Higgs pair production at the HL-LHC / Adhikary, Amit (Bangalore, Indian Inst. Sci.) ; Banerjee, Shankha (Durham U., IPPP ; Annecy, LAPTH) ; Barman, Rahool Kumar (Bangalore, Indian Inst. Sci.) ; Bhattacherjee, Biplob (Bangalore, Indian Inst. Sci.) ; Niyogi, Saurabh (Delhi U.)
We study the prospects of observing the non-resonant di-Higgs pair production in the Standard Model (SM) at the high luminosity run of the 14 TeV LHC (HL-LHC), upon combining multiple final states chosen on the basis of their yield and cleanliness. In particular, we consider the $b\bar{b}\gamma \gamma, b\bar{b} \tau^+ \tau^-, b\bar{b} WW^*, WW^*\gamma \gamma$ and $4W$ channels mostly focusing on final states with photons and/or leptons and study 11 final states.

The non-resonant and resonant Higgs pair production at the HL-LHC / Adhikary, Amit (Warsaw U. (main) ; Bangalore, Indian Inst. Sci.) ; Banerjee, Shankha (CERN) ; Barman, Rahool Kumar (Oklahoma State U.) ; Bhattacherjee, Biplob (Bangalore, Indian Inst. Sci.) ; Niyogi, Saurabh (Gokhale Coll., Calcutta)
Direct measurement of the Higgs self-coupling is crucial to understanding the nature of electroweak symmetry breaking, which requires observation of Higgs pair production. We study the prospects of observing the non-resonant Higgs pair production at the high luminosity run of the 14 TeV LHC (HL-LHC) upon considering various di-Higgs final states. [...]

Search for di-Higgs production at 13 TeV and prospects for the HL-LHC / Grimm, Kathryn (California State University) /ATLAS Collaboration
Di-Higgs final states can arise through non-resonant production of two Higgs bosons and through potential heavy states decaying to two Higgs boson. This talk presents searches in several Higgs boson decay channels using Run2 Data at 13 TeV. [...]
