Description
The measurement of the off-shell Higgs production and its decay width is performed in the Higgs decay channels of $ZZ\rightarrow 4\ell$ and $ZZ\rightarrow 2\ell2\nu$. The measurement uses Monte Carlo samples at a centre-of-mass energy of 13 TeV, produced according to the ATLAS detector configurations with an integrated luminosity of 139 fb$^{-1}$. The results are presented as an expected upper limit on the off-shell Higgs signal strength at 95% confidence levels (CLs). In addition, the $ZZ$ off-shell and on-shell combined results are shown.
