Lead ion collision event in CERN's CMS detector. Computer-generated graphic of the results of a collision between lead ions (PbPb collision), as observed by the CMS (Compact Muon Solenoid) detector of the Large Hadron Collider (LHC) at CERN, the European particle physics laboratory. During this event a candidate top quark and a candidate antitop quark were produced. From the top decays there are two b-jet candidates (shown by the orange cones), a muon (the isolated red line), and an electron (the green line and green tower). This experiment took place on 11 November 2018.
