Text: [Particle Physics] Pictorial representation in high-energy nuclear physics for data on the distribution of certain three-particle configurations. Many elementary particle decay processes and high-energy nuclear reactions lead to final states consisting of three particles (which may be denoted by a, b, c, with mass values ma, mb, mc). Well-known examples are provided by the K-meson decay process.
