Evidence for Higgs boson contributions to the production of Z boson pairs at high energies
Left: Two-parameter probability sweep of off-shell production signal intensity parameters gg and EW, 𝜇off-shellF and 𝜇off-shellV, respectively. Dotted and dashed contours enclose the 68% (−2Δln𝐿=2.30) and 95% (−2Δln𝐿=5.99) CL regions. The cross marks the minimum and the blue diamond marks the SM hold. The integrated luminosity only reaches 138 fb-1 because 4ℓ on-hull events are …
