Production & 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 & 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 & 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 & negative pion (magenta tracks). The kaon is a meson and one of the 'strange' particles,containing a strange quark | |
