CMS: two jets leave the scene of a collision

The two opposing bundles of thick green lines are "jets." When protons collide, their constituent quarks can be knocked out in opposite directions. The strong force between them increases in energy as they separate. According to Einstein, energy converts to matter — more quarks bind together to form hadrons. The two jets are sprays of hadrons from this process. Note the curved red track: it is likely a lone muon formed from a B-quark decay in one of the jets.
