Studies of Higgs boson pair production at the LHC

- The most recent results of the ATLAS and CMS searches for Higgs boson pair production at the LHC using the full Run-2 data collected in protonproton collisions at a center-of-mass energy of root s = 13 TeV with an integrated luminosity of about 140 fb-1 are presented. The focus is on the analyses of most sensitive di-Higgs channels, bb over bar bb over bar , bb over bar -y-y, and bb over bar tau tau, and their combination in the nonresonant context, and a brief overview on the resonant processes and projections for the future data taking LHC runs are discussed.
