The total decay width for a light Higgs boson with a mass in the observed range is not expected to be directly observable at the LHC. For the case of the Standard Model the prediction for the total width is about 4 MeV, which is three orders of magnitude smaller than the experimental mass resolution. There is no indication from the results observed so far that the natural width is broadened by new physics effects to such an extent that it could be directly observable. Furthermore, as all LHC Higgs channels rely on the identification of Higgs decay products, the total Higgs width cannot be measured indirectly without additional assumptions. The different dependence of on-peak and off-peak contributions on the total width in Higgs decays to ${{\mathit Z}}{{\mathit Z}^{*}}$ and interference effects between signal and background in Higgs decays to ${{\mathit \gamma}}{{\mathit \gamma}}$ can provide additional information in this context. Constraints on the total width from the combination of on-peak and off-peak contributions in Higgs decays to ${{\mathit Z}}{{\mathit Z}^{*}}$ rely on the assumption of equal on- and off-shell effective couplings. Without an experimental determination of the total width or further theoretical assumptions, only ratios of couplings can be determined at the LHC rather than absolute values of couplings.

The quoted value corresponds to $\Gamma _{H}$ $<$ $13.1$ MeV at 95$\%$ CL. The off-shell Higgs signal strength $\mu _{{\mathrm {off-shell}}}$ is measured to be $0.3$ ${}^{+0.9}_{-0.3}$ corresponding $\mu _{{\mathrm {off-shell}}}$ $<$ $3.4$ at 95$\%$ CL. The two off-shell signal strengths for ggF and EW production modes ($\mu {}^{{\mathrm {ggF}}}_{{\mathrm {off-shell}}}$, $\mu {}^{{\mathrm {EW}}}_{{\mathrm {off-shell}}}$) are measured to be $\mu {}^{{\mathrm {ggF}}}_{{\mathrm {off-shell}}}$ = $0.2$ ${}^{+1.3}_{-0.2}$ and $\mu {}^{{\mathrm {EW}}}_{{\mathrm {off-shell}}}$ = $0.4$ ${}^{+3.4}_{-0.4}$. 3  HAYRAPETYAN 2025L use 138 fb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV.

The tree-level Higgs-top Yukawa coupling is assumed to be the same for on-shell and off-shell Higgs boson production processes. Another assumption is that no BSM contributions affect the ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit t}}{{\overline{\mathit t}}}$ production. The quoted value is obtained by assuming the loop-induced ggF, ${{\mathit H}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$, and ${{\mathit H}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit \gamma}}$ rates can be modeled as a function of ${{\mathit \kappa}_{{{t}}}}$ and other SM couplings.

The off-shell Higgs signal strength is measured to be $1.1$ ${}^{+0.7}_{-0.6}$ assuming the same on-shell and off-shell coupling modifiers are used individually for gluon-fusion and for gauge-boson modes. The scenario of no off-shell contribution is excluded at 3.3 $\sigma $. Combining with the on-shell signal strength measurement, the total width normalized to its SM expectation $\Gamma _{H}/\Gamma {}^{SM}_{H}$ is measured to be $1.1$ ${}^{+0.7}_{-0.5}$ assuming the same on-shell and off-shell coupling modifiers are used individually for gluon-fusion and for gauge-boson modes.

The off-shell Higgs signal strength is measured to be $0.62$ ${}^{+0.68}_{-0.45}$ without the constraint on the ratio of the off-shell signal strengths for gluon-fusion and gauge-boson modes. The scenario of no off-shell contribution is excluded at 3.6 $\sigma $. The results are shown in their Table 1 with other constraint scenarios and the decay widths assuming the same coupling modifiers for on- and off-shell couplings (${{\mathit g}_{{{p}}}}$ and ${{\mathit g}_{{{d}}}}$ in their notation).
