| Abstract: We constrain the Higgs decay width using the off-shell production of Higgs bosons in their decay H $ \to $ WW $ \to $2$\ell $2$\nu $. The analysis uses proton-proton collision data with an integrated luminosity of 138 fb$ ^{-1} $ collected at a center-of-mass energy of $ \sqrt{s}= $ 13 TeV by the CMS experiment at the LHC. On- and off-shell signal strengths are used to derive the Higgs boson total decay width as $ \Gamma_{\mathrm{H}} = $ 3.9 $ ^{+2.7}_{-2.2} $ MeV, in agreement with the standard model value. This is an order of magnitude improvement over previous CMS results in this decay channel. | ||
