ATLAS-PHOTO-2024-046-2  -  Small, Medium, Large, Original
Event display of a proton-proton collision at √s=13 TeV recorded in the year 2018, selected in the high-ETmiss 2b category and classified as very signal-like by both the stop-NN and the DM-NN. The event is shown in a three-dimensional view in which the beampipe is the only visible part of the detector structure, together with a two-dimensional view in the xy-plane. Trajectories of charged particles reconstructed in the ID are shown in orange. Calorimeter deposits in the EM and hadronic calorimeters are shown with green and yellow volumes, respectively. The event contains a muon, whose trajectory is highlighted by a blue line passing through stations of the muon detectors. Four jets are highlighted by yellow cones, whose sizes are proportional to the transverse energies of the corresponding jets. The three jets close to each others form the multiplet of jets identified by the top-NN as the hadronic top candidate with a mass of 190 GeV and a pT of 506 GeV. The remaining jet is a b-tagged jet which forms together with the muon the leptonic top candidate. The reconstructed missing momentum, whose magnitude is ETmiss=544 GeV, is indicated by the white dashed line. Low-energy tracks and jets are not shown.

Event display of a proton-proton collision at √s=13 TeV recorded in the year 2017, selected in the boosted 2b-1t category and classified as very signal-like by the stop-NN. The event is shown in a three-dimensional view in which the beampipe and parts of the toroidal magnets are the only visible parts of the detector structure, together with a two-dimensional view in the xy-plane. Trajectories of charged particles reconstructed in the ID are shown in orange. Calorimeter deposits in the EM and hadronic calorimeters are shown with green and yellow volumes, respectively. The event contains a muon, whose trajectory is highlighted by a blue line passing through stations of the muon detectors. The large-R jet (indicated by the green cone) has a mass of 177 GeV and a pT of 615 GeV. The two yellow cones highlight the two b-tagged jets reconstructed in the event. The reconstructed missing momentum, whose magnitude is ETmiss=804 GeV, is indicated by the white dashed line. Low-energy tracks and jets are not shown.
