Event display of a candidate H→ Zγ event with the Z boson decaying μ+μ-. The transverse momenta of the two muon candidates, shown in red, are 72 GeV and 20 GeV. The photon candidate is reconstructed as an unconverted photon with a transverse momentum of 32.5 GeV. Two jets (R=0.4) are represented by light blue cones, with mjj of 965 GeV. The green boxes correspond to energy deposits in cells of the electromagnetic calorimeter, while yellow boxes correspond to energy deposits in cells of the hadronic calorimeter. The invariant mass of the Z boson candidate is 91.1 GeV and the invariant mass of Zγ system is 125.4 GeV. Image credit: ATLAS Collaboration / CERN.
