FORSCHUNG PHYSIK
Production and decay of a neutral kaon in the OPAL detector at CERN, the particle physics laboratory outside Geneva. The computer display shows the cylindrical detector in cross-section, outlined in white. An electron and positron, accelerated to high energy in CERN's LEP collider, have annihilated at the centre of OPAL. Their energy materialises in two bursts of particles (blue tracks leading to yellow and magenta blocks) and the neutral kaon. Being neutral, the kaon leaves no track, but is revealed by its characteristic V-shaped decay into a positive and negative pion (magenta tracks). The kaon is a meson and one of the 'strange' particles, containing a strange quark. (KEYSTONE/SCIENCE PHOTO LIBRARY/CERN) === ===
