Studying Same-Sign Top Pair Production through Top-Higgs FCNC Interactions at the HL-LHC

Figure 6

For the signal process, lepton distributions event regions: histogram clearly shows that final state is more favorable. The pair comes from the disintegration of pairs which have about 80 GeV rest mass. Hence, that energy and momentum shared by final particles give a peak around 40 GeV with boosted behavior. However, the same flavor final states shows an asymmetry originates from the following reasons: detector always discriminates lower and higher particle which gives a gap between first and second highest object. Nevertheless, they all have boosted behavior and give peaks close to 40 GeV as well.
