Two Higgs Doublets, a 4th Generation and a 125 GeV Higgs: A Review

Figure 19

𝑀^min_𝑙𝑏 for the SM4-like 𝑝𝑝→𝑡^′𝑡^′→2𝑊+2𝑏 signature (red) and for the 4G2HDMI 𝑝𝑝→𝑡^′𝑡^′→2𝑊+6𝑏 signature (blue) with 𝑚_𝑡′=350 GeV for a set of 7 TeV LHC events with ∫𝐿𝑑𝑡=5𝑓𝑏⁻¹ in the dilepton channel. The black line is plotted at the top mass and the region to the right of this line is the “signal region.” Figure taken from [149].
