Fig. 16.37 Distribution of the transverse mass of the Higgs boson candidates in the H → W W
decay channel, as observed by ATLAS at the time of discovery in summer 2012. The expected
signal for m H = 125 GeV is shown stacked on top of the overall background prediction
Fig. 16.38 Reduced coupling strength modifiers κ F m F /v for fermions (F = t, b, τ, μ) and
√ κ V m V /v for weak gauge bosons (V = W, Z) as a function of their masses m F and m V ,
respectively, where the vacuum expectation value of the Higgs field v = 246 GeV. The results
are obtained from ATLAS 13 TeV data and the SM prediction is also shown (dotted line). The
coupling modifiers κ F and κ V are measured assuming that there are no beyond-SM contributions to
the Higgs-boson decays or production processes. The lower inset shows the ratios of the measured
values to their SM predictions
