Evidence of off-shell Higgs boson production from $ZZ$ leptonic decay channels and constraints on its total width with the ATLAS detector

ATLAS Collaboration

This Letter reports on a search for off-shell production of the Higgs boson using 139 ${\text{fb}}^{-1}$ of $pp$ collision data at $\sqrt{s}=$ 13 TeV collected by the ATLAS detecto…
