Fully differential Higgs pair production in association with a W boson at next-to-next-to-leading order in QCD

Abstract To clarify the electroweak symmetry breaking mechanism, we need to probe the Higgs self-couplings, which can be measured in Higgs pair productions. The associated production with a vector boson is special due to a clear tag in the final state. We perform a fully differential next-to-next-to-leading-order calculation of the Higgs pair production in association with a W boson at hadron colliders, and present numerical results at the 14 TeV LHC and a future 100 TeV hadron collider.
