top pair production

Figures from CMS-DP-2015-019

Figure Description
Event display of a top-quark pair candidate in x-y views. This event has one isolated muon, one isolated electron and two hadronic jets both passing the tight threshold on the b-tagging discriminant.

Event display of a top-quark pair candidate in x-y views. This event has one isolated muon, transverse missing energy of 34 GeV, and five hadronic jets. Two of the jets pass the tight threshold on the btagging discriminant and are interpreted as originating from the b quarks from top quark decay. Two of the others form an invariant mass of 72 GeV and are interpreted as coming from a hadronically-decaying W boson. Leptonic top mass: 166 GeV. Hadronic top mass: 162 GeV.

single top t-channel

Figures from CMS-DP-2015-019

Event display of a single top quark t-channel candidate in x-y views. This event has one isolated muon, transverse missing energy of 27 GeV, and two hadronic jets. One of the jets passes the tight threshold on the Combined Secondary Vertex b-tagging discriminant and is interpreted as originating from the b quarks from top quark decay. The other jet has a pseudorapidity of -4.3 and in the signal ansatz it is interpreted as originating from a light quark recoiling against the top quark. The mass of the reconstructed top quark is 177 GeV.

ttZ production

Figures from PAS TOP-16-009

Figure Description
Display of the reconstructed tracks (green lines), calorimeter energy deposits (red for ECAL, blue for HCAL), jets (yellow cones), muons (red lines) and missing transverse energy (purple arrow) in one event selected in data, in which a pair of opposite sign muons with a mass close to the Z is reconstructed.

This event display corresponds to the same event as the previous one in the transverse plane.

Event Displays with 5.02TeV collisions

top pair production

Figure from PAS TOP-16-016

Figure Description
Event display of a candidate ttbar event selected in the 5.02 TeV dataset recorded by CMS. The figure depicts the CMS sub-detectors in the rho-phi plane. Calorimetric energy deposits in ECAL (HCAL) are depicted as red (blue) bars with a height proportional to the magnitude of the deposit. Tracks are represented by green (red) lines if reconstructed from tracker (tracker+muon system) hits. The measured kinematics of the reconstructed electron, muon, jets and missing transverse energy (EmissT) are represented next to each object.
