While the expectations for the measurement of the trilinear Higgs self-coupling are rather promising, an accurate measurement of the quartic self-coupling interaction is presently considered … WebA. Triple Higgs Boson Self-Coupling Via γγ → ffHH¯ (f = b,t) To illustrate our results of the sensitivity to the HHH triple Higgs boson self-coupling, we show the dependence of the cross-section on the center-of-mass energy of √ s = 500−3000 GeV for γγ → t¯tHH in Fig. 2 for several values of the Higgs boson mass M H = 120,140 GeV.
