Higgs boson pair production at the LHC in the b b W+ W- channel

Original · EN

We consider Higgs boson pair production at the LHC in the b b W+ W- channel, with subsequent decay of the W+W- pair into ℓ νj j. Employing jet substructure and event reconstruction techniques, we show that strong evidence for this channel can be found at the 14 TeV LHC with 600 fb⁻¹ of integrated luminosity, thus improving the current reach for the production of Higgs boson pairs. This measurement will allow to probe the trilinear Higgs boson coupling λ.
