Constraint on the total width of the Higgs boson from Higgs boson and four-top-quark measurements in $pp$ collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector

ATLAS Collaboration

This Letter presents a constraint on the total width of the Higgs boson (${\Gamma }_H$) using a combined measurement of on-shell Higgs boson production and the production of four top quark…
