abstract

A measurement of the mass of the Higgs boson combining the $H\to ZZ^{*} \to 4\ell$ and $H\to\gamma\gamma$ decay channels is presented. The result is based on 140 fb$^{-1}$ of proton-proton collision data collected by the ATLAS detector during LHC Run 2 at a centre-of-mass energy of 13 TeV combined with the Run 1 ATLAS mass measurement, yielding a Higgs boson mass of 125.11 $\pm$ 0.09 (stat.) $\pm$ 0.06 (syst.) = 125.11 $\pm$ 0.11 GeV. This corresponds to a 0.09 % precision achieved on this fundamental parameter of the Standard Model of particle physics.

    Using off-shell Higgs production in 138 fb^-1 of 13 TeV CMS data, the collaboration measured Γ_H = 5.1^{+2.0}_{-1.8} MeV, excluded no off-shell production at >5σ, and set the first direct 95% CL lower bound Λ_H > 870 ...

    Updated Gfitter EW fit with new MW average yields SM-consistent indirect observables and, via kappa_V from oblique parameters plus LHC signal strengths, determines Gamma_H to ~10% precision under leading-log assumptions.

    A dedicated boosted-jet category in HH→bbγγ is projected to narrow the κ2V constraint to [-0.4, 2.6] at 95% CL and improve heavy-resonance limits by 1–2x at 308 fb⁻¹.
