Fig. 3: A portrait of the Higgs boson couplings to fermions and vector bosons.
From: A portrait of the Higgs boson by the CMS experiment ten years after the discovery
Left: constraints on the Higgs boson coupling modifiers to fermions (κf) and heavy gauge bosons (κV), in different datasets: discovery (red), the full LHC Run 1 (blue) and the data presented here (black). The SM prediction corresponds to κV = κf = 1 (diamond marker). Right: the measured coupling modifiers of the Higgs boson to fermions and heavy gauge bosons, as functions of fermion or gauge boson mass, where υ is the vacuum expectation value of the BEH field (‘Notes on self-interaction strength’ in Methods). For gauge bosons, the square root of the coupling modifier is plotted, to keep a linear proportionality to the mass, as predicted in the SM. The P value with respect to the SM prediction for the right plot is 37.5%.
