Off-shell Higgs width extraction via HWW leptonic studies with the CMS experiment

Final state WW measurements in the mass range above 2$m_{W}$ provide a technique to measure the off-shell Higgs boson coupling strengths. This study presents the off-shell Higgs boson production yields via full Run II H $\rightarrow$ WW datasets, which are normalized to Standard Model predictions, where each W boson decays leptonically. The result of this study corresponds to an integrated luminosity of 138 $fb^{-1}$ at a center-of-mass energy of 13 TeV within CMS. Reweighting techniques are applied to model the off-shell signal prediction, and multiple Higgs boson pole masses are used to ensure signal sensitivity to off-shell productions. Methods for measuring the off-shell Higgs signal, $\mu$, include generating and weighting the proper samples, discriminating between production channels, and validating the shape yields by comparing simulations to data. Measuring the decay widths of an off-shell Higgs boson provides a way to calculate the complete Higgs width as the ratio of $\mu_{off-shell}$ to $\mu_{on-shell}$. This study provides a greater constraint on the Higgs width (theoretical value $4.1^{+5.0}_{-4.0}$ MeV), in conjunction with the H $\rightarrow$ ZZ studies.
