| contents | The Higgs boson (H) decay width is determined from the ratio of off- and on-shell production of H $\to$ WW $\to$ e$νμν$ using proton-proton collision data corresponding to an integrated luminosity of 138 fb$^{-1}$ collected at $\sqrt{s}$ = 13 TeV by the CMS experiment at the Large Hadron Collider. The off-shell signal strength is measured as $μ_\text{off-shell}$ = 1.2 $^{+0.8}_{-0.7}$. The Higgs boson total decay width is $Γ_\text{H}$ = 3.9 $^{+2.7}_{-2.2}$ MeV, in agreement with the standard model prediction. The uncertainty in this result represents a factor of three improvement over the previous CMS result in this decay channel. |
