Figure 1: Leading-order Feynman diagrams of the nonresonant production of Higgs boson pairs in the Standard Model through (a) the Higgs boson self-coupling and (b) the Higgs–fermion Yukawa interactions.
Table 1: List of MC generators and parton distribution functions of the signal and background processes used by the hh → bbττ and hh → γγWW ∗ analyses
Figure 2: Kinematic distributions of the hh → bbττ analysis after the preselection (see text) comparing data with the expected background contributions: (a) ditau mass m ττ reconstructed using the MMC method, (b) dijet mass m bb
