Description
Three-jet event. Electronic display of an electron-positron collision in the ALEPH detector at CERN, the European particle physics laboratory near Geneva. The display shows a cross-section of the detector, with the beam tube in the centre (blue) surrounded by various detector components (blue and red). The electron and positron, accelerated to high energy in CERN's LEP collider, annihilate at centre to create a quark and an antiquark, one of which radiates a gluon (carrier of the strong nuclear force). Although too short- lived to be detected directly, the quark, antiquark, & gluon each decays into jets of hadrons that spread out through the detector.
