Extended Data Fig. 8: Time evolution of the coupling measurements and their precision.
From: A portrait of the Higgs boson by the CMS experiment ten years after the discovery
(left) Comparison of the expected 1 SD uncertainties in the κ-framework fit including coupling modifiers for both tree-level and loop-induced Higgs boson interactions, in different datasets: at the time of the Higgs boson discovery, using the full data from LHC Run 1, in the dataset used in this paper, and the expected 1SD uncertainty for HL-LHC for \( {\mathcal L} =3000\,{{\rm{fb}}}^{-1}\). (right) Results of a fit to the coupling modifiers κ allowing both invisible and the undetected decay modes, with the SM value used as an upper bound on both κW and κZ. The thick (thin) black lines indicate the 1 (2) s.d. confidence intervals, with the systematic and statistical components of the 1 s.d. interval indicated by the red and blue bands, respectively. The p-value with respect to the SM prediction is 33%.
