Caption: Z particle decay in the UA1 detector at the CERN particle physics laboratory, Geneva. Discovered at CERN in 1983, the Z is one of the "carrier" particles which mediate the weak force. A proton & antiproton have collided & annihilated into pure energy in CERN's SPS collider. The energy rematerialises as a number of particles which include a Z; the Z is not visible because it immediately decays into other particles. In this computer display the UA1 detector is outlined in red. The Z has decayed into two high-energy muons (long white tracks) & two jets of other particles (short white & yellow tracks).
