Visualization of a data event from the tt¯H(γγ) Had BDT bin with the largest signal over background ratio; the event contains two photon candidates, with a diphoton mass of 125.4 GeV; in addition, six jets are reconstructed using the anti-kt algorithm and R = 0.4, including one jet that is b-tagged using a 77% efficiency working point; the photons correspond to the green towers in the electromagnetic calorimeter, while the jets (b-jets) are shown as yellow (blue) cones.
