Off-shell Higgs couplings in H⁎ → ZZ → ℓℓνν

We explore the new physics reach for the off-shell Higgs boson measurement in the pp→H⁎→Z(ℓ+ℓ−)Z(νν¯) channel at the high-luminosity LHC. The new physics sensitivity is parametrized in terms of the Higgs boson width, effective field theory framework, and a non-local Higgs-top coupling form factor. A...
