Figure 1: Scans of twice the negative log-likelihood ratio − 2 ln Λ ( m H ) as functions of the Higgs boson mass m H for the ATLAS and CMS combination of the H → γγ (red), H → ZZ → 4 ` (blue), and combined (black) channels
Figure 2: Summary of Higgs boson mass measurements from the individual analyses of AT- AT-LAS and CMS and from the combined analysis presented here
Table 1: Systematic uncertainties δm H (see text) associated with the indicated effects for each of the four input channels, and the corresponding contributions of ATLAS and CMS to the systematic uncertainties of the combined result
Figure 3 presents the impact of each group of nuisance parameters on the total systematic uncertainty in the mass measurement of ATLAS, CMS, and the combination
